Unable to upload files to Knowledge Base

Hi Team,

I’m currently building a Knowledge Base for an AI Agent use case and am unable to upload files successfully.

Issue: When I try to upload a file to the Knowledge Base, I receive an “Upload failed” error. I have tested this with both TXT and PDF files, but the same error occurs in each case.

Could you please advise what may be causing this issue and whether there are any specific file requirements, permissions, or configuration settings that need to be enabled for Knowledge Base uploads?
