Fix Lightning.Pub RPC integration for e2e cash-in flow
Major fixes: - Implement NIP-44 v1 encryption (Lightning.Pub requirement) - Fix RPC request format (rpcName, params, query, body, authIdentifier, requestId) - Fix PayInvoice amount field (always required, use 0 for invoices with amounts) - Fix NostrClient subscriptions to use direct Relay instead of SimplePool - Fix race condition by subscribing before publishing requests - Remove #p/#e tag filters and match manually (relay compatibility) New features: - Add CLINK Debit support to cash-in flow - Add invoice paste input for manual payments - Add Input UI component Documentation: - Add TROUBLESHOOTING.md with 6 non-obvious integration gotchas - Update CLAUDE.md with reference to troubleshooting doc Test scripts: - fund-dev.mjs - Create invoices for testing - test-pay.mjs - Test PayInvoice RPC directly Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

# Lightning.Pub Integration Troubleshooting
|
||||
|
||||
This document captures hard-won lessons from debugging the Lightning.Pub RPC integration. Read this before debugging payment issues.
|
||||
|
||||
## Quick Checklist
|
||||
|
||||
If payments are "hanging" (no response), check in this order:
|
||||
|
||||
1. **Is the payment actually going through?** Check Lightning.Pub logs:
|
||||
|
||||
```bash
|
||||
docker logs lamassu-lightning-pub --tail 20
|
||||
```
|
||||
|
||||
Look for "invoice paid X sats" - if you see this, the payment worked but the response isn't reaching your client.
|
||||
|
||||
2. **Are you receiving ANY events?** Add logging to your subscription's `onEvent` callback. If nothing fires, it's a subscription issue (see Issue #3 below).
|
||||
|
||||
3. **Is the response for you?** Check if events are being filtered correctly by `#p` tags and `requestId`.
|
||||
|
||||
---
|
||||
|
||||
## Issue #1: RPC Request Format
|
||||
|
||||
### Symptom
|
||||
|
||||
```
|
||||
ERROR NewInvoiceRequest::root.: object is not an instance of an object
|
||||
```
|
||||
|
||||
### Cause
|
||||
|
||||
Lightning.Pub expects a specific RPC request structure. Missing fields cause cryptic errors.
|
||||
|
||||
### Solution
|
||||
|
||||
Always include ALL fields in the RPC request:
|
||||
|
||||
```typescript
|
||||
const request = {
|
||||
rpcName: 'PayInvoice', // Method name
|
||||
params: {}, // URL params (usually empty)
|
||||
query: {}, // Query params (usually empty)
|
||||
body: { invoice, amount }, // Method-specific data
|
||||
authIdentifier: identity.publicKey, // Your pubkey
|
||||
requestId: uniqueId, // For matching responses
|
||||
}
|
||||
```
|
||||
|
||||
**Common mistake:** Putting method params directly in the request object instead of inside `body`.
|
||||
|
||||
---
|
||||
|
||||
## Issue #2: PayInvoice Amount Field
|
||||
|
||||
### Symptom
|
||||
|
||||
```
|
||||
ERROR PayInvoiceRequest::root..amount: is not a number
|
||||
```
|
||||
|
||||
or
|
||||
|
||||
```
|
||||
ERROR invoice has value, do not provide amount in the request
|
||||
```
|
||||
|
||||
### Cause
|
||||
|
||||
The `amount` field has confusing semantics:
|
||||
|
||||
- It's ALWAYS required (despite the second error message suggesting otherwise)
|
||||
- For invoices WITH amounts: send `amount: 0` (meaning "use invoice amount")
|
||||
- For amountless invoices: send the actual amount
|
||||
|
||||
### Solution
|
||||
|
||||
```typescript
|
||||
const body = {
|
||||
invoice: paymentRequest,
|
||||
amount: invoiceHasAmount ? 0 : amountSats,
|
||||
}
|
||||
```
|
||||
|
||||
**Why this is confusing:** The error "do not provide amount" is misleading. You must provide it, but set it to 0.
|
||||
|
||||
---
|
||||
|
||||
## Issue #3: Subscription Not Receiving Events
|
||||
|
||||
### Symptom
|
||||
|
||||
- Payment succeeds (visible in Lightning.Pub logs)
|
||||
- Client subscription's `onEvent` never fires
|
||||
- EOSE is received but no real-time events
|
||||
|
||||
### Cause
|
||||
|
||||
`SimplePool.subscribeMany()` from nostr-tools doesn't reliably deliver real-time events. It works for historical queries but not for waiting on responses.
|
||||
|
||||
### Solution
|
||||
|
||||
Use direct `Relay.subscribe()` instead of the pool:
|
||||
|
||||
```typescript
|
||||
// DON'T use pool for real-time subscriptions
|
||||
const sub = pool.subscribeMany(urls, filters, { onevent: ... })
|
||||
|
||||
// DO use direct relay connection
|
||||
const relay = await Relay.connect(url)
|
||||
const sub = relay.subscribe(filters, { onevent: ... })
|
||||
```
|
||||
|
||||
If using a client wrapper, ensure subscriptions go through the connected Relay instances, not through SimplePool.
|
||||
|
||||
---
|
||||
|
||||
## Issue #4: Race Condition - Missing Responses
|
||||
|
||||
### Symptom
|
||||
|
||||
- First payment always times out
|
||||
- Subsequent payments sometimes work
|
||||
- Response arrives before subscription is ready
|
||||
|
||||
### Cause
|
||||
|
||||
Lightning.Pub responds VERY fast. If you publish the request before setting up the subscription, the response arrives before you're listening.
|
||||
|
||||
### Solution
|
||||
|
||||
Always set up the subscription BEFORE publishing:
|
||||
|
||||
```typescript
|
||||
// WRONG - race condition
|
||||
await nostrClient.publish(event)
|
||||
const response = await waitForResponse(requestId)
|
||||
|
||||
// RIGHT - subscribe first
|
||||
const responsePromise = waitForResponse(requestId) // Sets up subscription
|
||||
await nostrClient.publish(event) // Then publish
|
||||
return responsePromise // Then wait
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Issue #5: Tag Filters Not Working
|
||||
|
||||
### Symptom
|
||||
|
||||
- Subscription with `#p` filter receives no events
|
||||
- Same subscription without `#p` receives events
|
||||
|
||||
### Cause
|
||||
|
||||
Some Nostr relays (including strfry in some configurations) don't properly support tag filters in subscriptions.
|
||||
|
||||
### Solution
|
||||
|
||||
Subscribe to a broader filter and manually check tags:
|
||||
|
||||
```typescript
|
||||
// Instead of relying on relay to filter by #p
|
||||
const sub = relay.subscribe(
|
||||
[
|
||||
{
|
||||
kinds: [21000],
|
||||
authors: [lightningPubPubkey],
|
||||
// '#p': [myPubkey], // DON'T rely on this
|
||||
},
|
||||
],
|
||||
{
|
||||
onevent: (event) => {
|
||||
// Manually check p-tags
|
||||
const pTags = event.tags.filter((t) => t[0] === 'p')
|
||||
if (!pTags.some((t) => t[1] === myPubkey)) {
|
||||
return // Not for us
|
||||
}
|
||||
// Process event...
|
||||
},
|
||||
}
|
||||
)
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Issue #6: Response Matching with #e Tag
|
||||
|
||||
### Symptom
|
||||
|
||||
- Using `#e` filter to match responses to requests
|
||||
- No events received
|
||||
|
||||
### Cause
|
||||
|
||||
Lightning.Pub doesn't include an `e` tag referencing the request event in its responses. It only uses `p` tags.
|
||||
|
||||
### Solution
|
||||
|
||||
Match responses by `requestId` in the decrypted content, not by event tags:
|
||||
|
||||
```typescript
|
||||
onevent: (event) => {
|
||||
const response = decryptJSON(identity, pubkey, event.content)
|
||||
|
||||
// Match by requestId, not by #e tag
|
||||
if (response.requestId !== expectedRequestId) {
|
||||
return // Not our response
|
||||
}
|
||||
// Process response...
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Debugging Tools
|
||||
|
||||
### Test Script
|
||||
|
||||
Use a standalone test script to isolate issues:
|
||||
|
||||
```javascript
|
||||
// test-pay.mjs
|
||||
import { Relay } from 'nostr-tools/relay'
|
||||
|
||||
const relay = await Relay.connect('ws://192.168.1.122:7777')
|
||||
|
||||
// Subscribe BEFORE publishing
|
||||
const sub = relay.subscribe(
|
||||
[
|
||||
{
|
||||
kinds: [21000],
|
||||
authors: [LIGHTNING_PUB_PUBKEY],
|
||||
},
|
||||
],
|
||||
{
|
||||
onevent(evt) {
|
||||
console.log('Got event:', evt.id)
|
||||
// Decrypt and check requestId...
|
||||
},
|
||||
}
|
||||
)
|
||||
|
||||
await relay.publish(signedEvent)
|
||||
```
|
||||
|
||||
### Lightning.Pub Logs
|
||||
|
||||
```bash
|
||||
# Watch for payment activity
|
||||
docker logs -f lamassu-lightning-pub 2>&1 | grep -E "pay|invoice|ERROR"
|
||||
```
|
||||
|
||||
### Relay Logs
|
||||
|
||||
```bash
|
||||
# Watch relay traffic
|
||||
docker logs -f lamassu-relay
|
||||
```
|
||||

||||

|
||||
|
||||
## Summary of Correct Implementation
|
||||
|
||||
```typescript
|
||||
async sendRPC<T>(rpcName: string, body: unknown): Promise<T> {
|
||||
const requestId = generateUniqueId()
|
||||
|
||||
const request = {
|
||||
rpcName,
|
||||
params: {},
|
||||
query: {},
|
||||
body,
|
||||
authIdentifier: this.identity.publicKey,
|
||||
requestId,
|
||||
}
|
||||
|
||||
const encrypted = encryptNIP44(this.identity, targetPubkey, request)
|
||||
const event = finalizeEvent({
|
||||
kind: 21000,
|
||||
content: encrypted,
|
||||
tags: [['p', targetPubkey]],
|
||||
created_at: now(),
|
||||
}, this.identity.privateKey)
|
||||
|
||||
// 1. Subscribe FIRST (before publishing)
|
||||
const responsePromise = new Promise((resolve, reject) => {
|
||||
const timeout = setTimeout(() => reject(new Error('Timeout')), 30000)
|
||||
|
||||
// 2. Use direct relay, not pool
|
||||
const sub = this.relay.subscribe([{
|
||||
kinds: [21000],
|
||||
authors: [targetPubkey],
|
||||
// 3. Don't use #p filter - check manually
|
||||
}], {
|
||||
onevent: (evt) => {
|
||||
// 4. Manual p-tag check
|
||||
if (!evt.tags.some(t => t[0] === 'p' && t[1] === myPubkey)) return
|
||||
|
||||
const response = decrypt(evt.content)
|
||||
|
||||
// 5. Match by requestId, not #e tag
|
||||
if (response.requestId !== requestId) return
|
||||
|
||||
clearTimeout(timeout)
|
||||
sub.close()
|
||||
|
||||
if (response.status === 'ERROR') {
|
||||
reject(new Error(response.reason))
|
||||
} else {
|
||||
resolve(response)
|
||||
}
|
||||
}
|
||||
})
|
||||
})
|
||||
|
||||
// 6. Publish AFTER subscription is set up
|
||||
await this.relay.publish(event)
|
||||
|
||||
return responsePromise
|
||||
}
|
||||
```
|
||||

## Time Spent on Each Issue
|
||||
|
||||
| Issue | Time to Diagnose | Root Cause |
|
||||
| -------------- | ---------------- | ---------------------------------------- |
|
||||
| RPC format | ~30 min | Missing `params`, `query` fields |
|
||||
| Amount field | ~45 min | Confusing `0` vs actual amount semantics |
|
||||
| SimplePool | ~60 min | Pool doesn't deliver real-time events |
|
||||
| Race condition | ~15 min | Subscribe before publish |
|
||||
| Tag filters | ~30 min | Relay doesn't support #p filter properly |
|
||||
| #e matching | ~20 min | Lightning.Pub doesn't use e-tags |
|
||||
|
||||
**Total debugging time: ~3+ hours**
|
||||
|
||||
Following this document should reduce that to ~15 minutes.
