The File Search function stopped working.

[jmartinezb3]

What happened?

Using the Agents endpoint (and also the legacy ones), when uploading a PDF, the models are not able to detect the file. I have tested with both Azure OpenAI and Google models.

My embeddings configuration is set via Azure OpenAI, the environment variables are properly configured, and everything had been working well until recent versions of the LibreChat app.

According to the Azure dashboard, the embedding model has indeed consumed tokens, so I assume that process is working correctly. The OCR method works fine across all endpoints.

In the LibreChat logs, there are no error warnings, so whatever is happening is not being detected as an issue.

.env Azure OpenAI Embedding configuration:

# Azure OpenAI RAG API
EMBEDDINGS_PROVIDER=azure
RAG_AZURE_OPENAI_API_KEY=[REDACTED]
RAG_AZURE_OPENAI_ENDPOINT=https://[REDACTED].openai.azure.com
RAG_AZURE_OPENAI_API_VERSION=2025-01-01-preview
EMBEDDINGS_MODEL=text-embedding-3-large

On the latest version of LibreChat:

Make sure file search is toggled for this agent. Also, if you have the right capabilities configured:

endpoints:
  agents:
# at minimum, you need `file_search` or leave this out to enable all capabilities
    capabilities: ["file_search"]

[jmartinezb3]

Thank you for your response, where can I use that configuration?

endpoints:
  agents:
# at minimum, you need `file_search` or leave this out to enable all capabilities
    capabilities: ["file_search"]

In the .yaml? Is it in the documentation?

[jhmonroe]

In YAML it says # # (optional) Agent Capabilities available to all users. Omit the ones you wish to exclude. Defaults to list below.
So not sure why this would matter if it was all commented out (which is the default) in your YAML...?
