Required azureOpenAIApiInstanceName with non-OpenAI models

[weipienlee]

What happened?

Model can not be used with agent endpoint, yields log:

LibreChat | 2025-03-18 19:40:09 error: [api/server/controllers/agents/client.js #titleConvo] Error azureOpenAIApiInstanceName is required when using azureOpenAIApiKey

note: this is not an Azure OpenAI Service but an Azure AI Service, however, it's config does work under LibreChat's Azure OpenAI endpoint.

Steps to Reproduce

1. Add endpoints: azureOpenAI: groups: group to librchat.yaml

and add non-OpenAI model config (assumed already deployed)

serverless: true
instanceName: <my Azure AI Foundry Hub Project name> 
apiKey: "${AZURE_AI_API_KEY}"
baseURL: "${AZURE_AI_ENDPOINT}"
models:
    Phi-4-multimodal-instruct: true

2. Check if model config works with the LibreChat's "normal" Azure OpenAI endpoint
3. If so, create an agent with that model (default settings)
4. Save and Select
5. Send "hi" (already error without tool)

note: I have another Azure OpenAI group config with OpenAI models. Removing those makes no difference, though.

Apologies, I mistook your config for a misconfiguration error, I'll look into this soon

[weipienlee]

I mirrored that example by:

1. removing instanceName
2. add version

but same results with Agent endpoint. Note, the model works with Azure endpoint in LibreChat
