I see this a lot in Prosody error.log: Apr 01 14:35:42 c2s55c83a2de3d0 error Traceback[c2s]: /usr/share/lua/5.2/prosody/util/error.lua:144: attempt to index local 'error_tag' (a nil value) stack traceback: /usr/share/lua/5.2/prosody/util/error.lua:144: in function 'from_stanza' /usr/share/lua/5.2/prosody/core/moduleapi.lua:411: in function '?' /usr/share/lua/5.2/prosody/util/events.lua:81: in function </usr/share/lua/5.2/prosody/util/events.lua:77> (...tail calls...) ...sody-modules/mod_log_slow_events/mod_log_slow_events.lua:12: in function <...sody-modules/mod_log_slow_events/mod_log_slow_events.lua:10> (...tail calls...) /usr/share/lua/5.2/prosody/util/events.lua:81: in function </usr/share/lua/5.2/prosody/util/events.lua:77> (...tail calls...) ...sody-modules/mod_log_slow_events/mod_log_slow_events.lua:12: in function <...sody-modules/mod_log_slow_events/mod_log_slow_events.lua:10> (...tail calls...) /usr/share/lua/5.2/prosody/core/stanza_router.lua:188: in function 'core_post_stanza' /usr/share/lua/5.2/prosody/core/stanza_router.lua:128: in function 'core_process_stanza' /usr/lib/prosody/modules/mod_c2s.lua:326: in function 'func' /usr/share/lua/5.2/prosody/util/async.lua:144: in function </usr/share/lua/5.2/prosody/util/async.lua:142> What version of the product are you using?

Thanks for the report. I have no idea what's going on here, the traceback contains no clue as to why this happened or which module is using the module:send_iq() API, only that somehow it's trying to convert a stanza to an error object, but the stanza doesn't have an <error> payload. It Debian Buster is no longer supported, you should upgrade.

Hey Zash, thank you for fixing it. :-) And yes, I already upgraded the server to Bullseye, finally... But the error is still there, Bullseye, Lua 5.4 and Prosody 0.12 (1nightly200-1~bullseye). Will the fix make it into the nightlies of 0.12? Regards, Roi

> Will the fix make it into the nightlies of 0.12? Yes, should be tomorrow. Also the next 0.12.x minor release, whenever that happens (undecided at this point).

Great, thank you again! And it does not matter if tomorrow or in a few days. :-)
