Describe your problem

Chat doesn't retrieve answer from knowledge. The knowledge is worked when I use the search. I start ragflow docker base on latest git main version. After I uplaod a document. I meet one strange issue that the chat can not search the query content, but I can manually query content in knowledge.

I searched the log of docker-ragflow-cpu-1, find several logs show errors while server executed some tasks.

when I use workfolw to define a agent and test. I found an error
