As suggested by @DmitriyAlergant-T1A a bug report for this issue

Discussed in https://github.com/open-webui/open-webui/discussions/7585

Originally posted by Xelaph December 3, 2024
I imported the following pipe function: https://openwebui.com/f/haervwe/arxiv_web_research_mcts_pipe
However, I forgot to set the model-id required by the function. When I tried to use the function from the main UI, I got a blank screen where I can't do anything no matter what page I try to go to. This persists over restarts.

I'm running the ghcr.io/open-webui/open-webui:ollama container
I get the following error in the logs:

Original GitHub issue: https://github.com/open-webui/open-webui/issues/7595 As suggested by @DmitriyAlergant-T1A a bug report for this issue ### Discussed in https://github.com/open-webui/open-webui/discussions/7585 <div type='discussions-op-text'> <sup>Originally posted by **Xelaph** December 3, 2024</sup> I imported the following pipe function: https://openwebui.com/f/haervwe/arxiv_web_research_mcts_pipe However, I forgot to set the model-id required by the function. When I tried to use the function from the main UI, I got a blank screen where I can't do anything no matter what page I try to go to. This persists over restarts. I'm running the ghcr.io/open-webui/open-webui:ollama container I get the following error in the logs: ``` File "/usr/local/lib/python3.11/site-packages/starlette/_utils.py", line 93, in
