chenyukang commented 4 weeks ago

I'm not sure whether we should fix it.

The error code is implemented with reference of BOLTS: https://github.com/lightning/bolts/blob/master/04-onion-routing.md#returning-errors

We need to get a balance between privacy and convenience of identifying the specific cause of the error.

sunchengzhu commented 4 weeks ago

I have the same confusion. I focused only on the error message returned by the send_payment RPC and overlooked the node logs, which made it take me a long time to pinpoint the cause of the error.
