nostr:npub1syjmjy0dp62dhccq3g97fr87tngvpvzey08llyt6ul58m2zqpzps9wf6wl Are you able to zap nostr:npub12262qa4uhw7u8gdwlgmntqtv7aye8vdcmvszkqwgs0zchel6mz7s6cgrkj using jumble.social? I'm am repeating the following issue:
1. I am able to zap @semisol from Yakihonne (web) and Nostrudel (web)
2. On Jumble.social I get "failed to create invoice".
Might be an interesting test case for you to debug if you can reproduce the issue
Are you using anon zaps by any chance?
No, nothing special or unusual.
Odd…
Zapped
nostr:npub1syjmjy0dp62dhccq3g97fr87tngvpvzey08llyt6ul58m2zqpzps9wf6wl Yes, I think I have a good repeatable issue for you -- I am able to zap nostr:npub12262qa4uhw7u8gdwlgmntqtv7aye8vdcmvszkqwgs0zchel6mz7s6cgrkj with Coracle, Yakihonne, and Nostrudel, but with jumble.social I get "failed to create invoice".

The latest version of nostr-tools builds zapRequests with a k tag, but nostr:npub12262qa4uhw7u8gdwlgmntqtv7aye8vdcmvszkqwgs0zchel6mz7s6cgrkj’s lnurl server doesn’t support it.
Could you make such error texts visible to the user? Thanks.
I have added support for k.
fix confirmed! I am now able to zap nostr:npub12262qa4uhw7u8gdwlgmntqtv7aye8vdcmvszkqwgs0zchel6mz7s6cgrkj with jumble.social!
