@ChMat commented on GitHub (Jan 26, 2025):

I’m experiencing the same error message within Open Web UI GUI.

Same configuration as OP, I just upgraded from previous versions of Ollama and Open Web UI.

I’m trying to change Embedding model to bge-m3:latest and I get the TypeError: 'NoneType' object is not iterable error when I try to upload files or edit text content into a documentation.

I’m runnings Open Web UI in WSL and using latest version of Chrome as my browser.

Rolling back to the default Embedding model engine (sentence transfomers) makes the error disappear.
