📄 Description

Description

This fixes an issue with RAG scan that stops loading documents as soon as it reaches a file with unsupported mime type (or any other exceptions).
When the mime type is not supported, the scan operation stops with 'NoneType' object has no attribute 'find'.

Sample unsupported mime type: triage_process.graffle

Explanation of changes

Check if file_content_type is not None before searching for text/ and use TextLoader
Move try/except into the for loop so that we continue loading next files even if loading a document fails.
In case of the triage_process.graffle we fallback to TextLoader, but it seem to fail with loading, so we continue with the next document.
