[Bug]: Files cannot be uploaded to Azure Assistants

[mansiibm]

What happened?

Hi, thanks for the RAG update!!! . I am using the dev version - danny-avila/librechat-dev-api:3ba7c4eb19d136680ae5c31c27e1cd025bfd80fa and the latest RAG.

For my azure assistants , I am unable to upload the files. The versions of the apis I tried-

2024-02-15-preview
2025-01-01-preview

Both are not helping assistant to work with the files.

Rag- danny-avila/librechat-rag-api-dev:19d8f4d86856f4d165e7d38086ec660a4861be9e

Hi, thanks for the fix to upload the files to assistant :)

Today, I applied today - the lc version- ghcr.io/danny-avila/librechat-dev-api:57faae8d96dc86441a90cfc6cea558b9922df840
with existing rag version- ghcr.io/danny-avila/librechat-rag-api-dev:f7a3254529b07ff951472618d9499f0772a48138 for LC setup in azure.

Problem statement: Files uploaded to all endpoints apart from azureAssistants, can be deleted but not the one's attached to the latter from manage files section before today.

Steps followed-

1. I upload a file to the azure assistant -

2. I want to delete from manage files section -

3. The file appears there I delete it

file.is.deleted.-2.april.mp4

4. The file is deleted I try deleting the 13 March file-

20250402-0755-12.7358962.mp4

5. All the files I had for other endpoints the older ones I can delete them, but azure assistants are not getting deleted. The older ones specifically.

Is some extra config required? I even have the azure blob storage for image and for file , by the name - rag-uploads. I am using vcore database in azure. Thanks.

And also I do not have any of these files in my studio from 13 March -
