The bot is joining my channel muted and when I try and play from webui it says its can't find a node.

I've looked into the code and I aactually had the concern that the Lavaplayer API has changed again (which once happened before and caused exceptions with yuri). I've upgraded our own Lavalink instance and tested around with our yuri2 instance, but I could not reproduce the error.

This is the image hash of the used Lavalink (fredboat/lavalink:master) instance:

sha256:8e21add319415de240a357bfda0afdd21282ed2c4def8266760b34bdb91af189

I've found some lines in the code where the mentioned strconv.Atoi function is implemented, but no one of these actually should cause the error.

Can you maybe explain when exactly the issue occurs? Can you reproduce it reliably? When yes, how? Which version of Lavaplayer are you hosting? How does you hosting environemnt look like (Docker? Linux? Windows? ...).

Would be nice if you can give me these information so I can dig deeper into the problem.

The issue occurs right when I start yuri2.

Tank you verry much.

I've tested around a bit and I got the same issue. The problem was caused by the gavalink package (wrapper for the Lavalink API). I've fixed the issue a while ago with this pull request and then changed the dependency to the original one instead of my fork, but on build it might have downloaded the version of the v.1.0.0 tag instead of the latest commit which includes my fix.

TL;DR: I've now hard-locked the gavalink dependency to the latest working commit which should fix the issue. This should also fix the No nodes present issue. At least I could not reproduce it anymore.

To be completely sure the issue is fixed, could you please download the build artifact from this CI job and test if the issue consists:

I no longer get the PLAYER error. My bot boots up without error and I can see all my audio files but when I click on a sound I get this message in my lavalink console.

The bot joins muted as well.

Also the WebUI is completely different then the one in this Yuri2 github. Are the features still available for adding your own favorites?

This new UI doesn't have the options for chaining sounds or adding favorites.

This is the error I get in the webui when I click a sound.

Getting this same error with all sound files,
