Setting up llm-graph-builder: Unable to get response from backend

Hi All!

I'm trying to setup the llm-graph-builder app on google cloud. But can't seem to get the pdf to be parsed. The same pdf works on the demo site but not on mine.
I get this error:

Failed To Process File:Pityriasis rosea.pdf or LLM Unable To Parse Content invalid literal for int() with base 10: ''

Based on what I understand the int() with base 10 error is there because the system is getting an empty string at some point.

I'm not sure what I'm doing wrong.

Initially I had trouble getting the backend and frontend to communicate then I added the backend url to the dockerfile, line 3 here.

Now I am able to upload files, connect to the database etc, but unable to parse anything.

Would be glad to get some help!
