0.4.0rc3 causing OctoPrint to failed to start #56

Closed Largoat closed 1 year ago

Largoat commented 1 year ago

I've been trying to get Multicam working on OctoPrint 1.9. I switched to RC stream for Multicam which installed 0.4.0rc3 and since them I got an error on start up. I removed the plugin and now I boot up fine.

This is due to a known bug in Octoprint 1.9.0, and unfortunately will not be fixed until the Octoprint 1.9.1 update. There is a bug reported on the Octoprint Repository with an updated Core.py file that fixes the issues, but you will need to manually update the Octoprint Core File to fix it, or just wait for the patch: https://github.com/OctoPrint/OctoPrint/issues/4818
