Strange they use the same library for serialization and verification.

but clnurl does not check the description, right? also I used a .js tool to check the descriptions signature and id, all valid.

Maybe I'm misunderstanding where it's failing. Do you have the text of the log message you're seeing ?

plugin-cln-zapper: Error while decoding zap (likely just not a zap invoice): invalid signature

Going to have to look into this further. But my guess is it's because some of the relays have a trailing /. That's lost when serializing to a rust url type. Will have to figure out how to handle that. Would have been introduced here. https://github.com/thesimplekid/cln-zapper-rs/commit/281bc4321b38af99e43161a99422c634f433490b

Just do the verification on a simple string to json object without fancy url-types. you can do that after the verification.

I thought rust types were supposed to be helpful lol. Pushed that for now. https://github.com/thesimplekid/cln-zapper-rs

If you got that then its verifying i belive, is it working? I do see 23 sats on this post but not sure if youre using youre other zapper. Never seen that TLS error before

yes, it works. but I think because you commented out the verification.

No, I realized Event from json does verification so dont need to call it manually. https://docs.rs/nostr/0.20.0/src/nostr/event/mod.rs.html#94-101

also got this somewhere at start: **BROKEN** plugin-cln-zapper: TLS alert received: AlertMessagePayload {\n level: Fatal,\n description: InternalError,\n}
