Unknown command 'listpays'

[ghost]

Issue and Steps to Reproduce

Sometimes (this happened a few times now) and maybe when interacting with spark-wallet, c-lightning loses listpays and responds:

{
   "code": -32601,
   "message": "Unknown command 'listpays'"
}

After a restart it knows about listpays again :-)

getinfo output

version: "v0.9.0-2-ge7d89cd"

The plugin crashed for some reason, can you share your log?

[ghost]

Oh you are right but I restarted c-lightning again and the log is gone (output of lightningd). Stupid me! I will include it when it happens again.

[vincenzopalazzo]

😄 Yep don't worry. I suggest (if you can) you to use the next release of lightningd (9.0.1) because include some refactoring inside the listpays, like #3915 but add also a little refactoring inside the format of the response more here #3888.

I will but only when spark-wallet is also up-to-date.

PR #3890 should also crash lightningd if any of the builtin plugins crash, which should help us debug, if you are willing to run on master and possibly have C-lightning crash outright.

I'm now on master and spark-wallet is still fine.

I'm pretty sure this is just another instance of #3915, which will be fixed by #3927 👍

Ok I close it for now
