Can't upload .txt or .py files into LibreChat for use with Deepseek

[driftywinds]

What happened?

I keep getting the Error Processing File pop up after trying to upload. I run LibreChat with Docker compose and a librechat.yaml for Deepseek as a custom endpoint, does anyone know what I need to change in the config to support the uploads?

Version Information

latest

Steps to Reproduce

1. Configure deepseek in librechat.yml, start the container
2. make a new chat, try uploading the files

What browsers are you seeing the problem on?

Firefox
