Additional Information
The error occurs while using the langchain library for processing PDF documents.
The issue appears to be related to image extraction and processing from the PDF.
The system is attempting to reshape an array of size 294 into a shape of (300, 152, newaxis), which is not mathematically possible.
This resulted in a 400 Bad Request response for the POST request to "/rag/api/v1/process/doc".
