[HELP] document-summarizer error message for some PDF files

[CedricGoby]

Hi,

I'm using the docker version of Anything LLM and Chroma

mintplexlabs/anythingllm:master
chromadb/chroma:0.5.1.dev173

The docker host is a small VM with 2 CPU, 4 Go RAM and no GPU.

The LLM is "mistral-large-2204", the vector database is "Chroma" and the embedder is the default "AnythingLLM Embedder".

I have 2 PDF files in my workspace : a small one and a bigger one.

If I ask the agent to summarize those PDF files it works for the small one :

[backend] info: [TELEMETRY SENT] {"event":"sent_chat","distinctId":"0ecf90ec-3ef0-4b37-97a6-bc15ff5d91b4","properties":{"multiUserMode":false,"LLMSelection":"mistral","Embedder":"native","VectorDbSelection":"chroma","runtime":"docker"}}

But there is an error for the bigger PDF file :

Can you help me to understand what's wrong in that case ?
