Error 400 - Sending to Discord

[kmadaras]

I am running the latest release for docker, and it just stopped working for Discord.

My config looks like this:

configs:
"@":
urls:
- discord://116282579146/zn0S_c_pMFh1o5U68yT7Msef_8TgXPCXEwpZ3oEf_ZMFJ54b8Uc

This is the same config I've been using for quite some time with no issues, yet now all the emails are getting rejected. The logs say:

I've tried a new webhook, just to be sure there's no problem there, same issue.

Any ideas? Perhaps we need an update to the Discord library?

Thanks!

Note, I redacted the server names and email adresses.

Could you get another log with the latest image? I've added some additional logging that will tell us more about the contents of your messages.

From what I've seen, if there's a problem with Discord, it tends to be that the emails produce messages that are too large for the service. Did you recently stop using Nitro?

I am facing the same issue. Is there a way to split or truncate messages that exceed Discord's 2000 character message limit?
