After checking journalctl, I only see 1 type of warning

I've tested with all functions and actions disabled to no avail. I believe it's related to the knowledge because this error only began occurring consistently when I added knowledge from the workspace to the model.

@Aareon commented on GitHub (Feb 10, 2025):

Can confirm this issue occurs only when knowledge is added to the custom model. Upon removing the knowledge, the model has no issue outputting.
