How are you running AnythingLLM?

AnythingLLM desktop app

What happened?

I'm testing 3 pdf file, 2 files successfully created in pgvector.
While 1 file getting log error like this:

....
[backend] info: [NativeEmbedder] Embedded Chunk Group 68 of 69
[backend] info: [NativeEmbedder] Embedded Chunk Group 69 of 69
[backend] info: [PGVectorDb] Inserting vectorized chunks into PGVector collection.

One file likely contains \u0000 somewhere in it in unicode - which will always fail on upsert of jsonb column types. Do you have the file available that you can share so we can reproduce the bug?
