titleConvo fails to load Custom Endpoint Config, causing timeout with OpenRouter

[BersteinMilza]

What happened?

When using a OpenRouter custom endpoint with titleConvo: true, the title generation process often fails with a "Title generation timeout" error. The root cause appears to be a failure to load the custom endpoint configuration, as indicated by the warning [api/server/controllers/agents/client.js #titleConvo] Error getting endpoint config in the logs.
Chats titles remain "New Chat"

Steps to Reproduce

1. Configure a custom endpoint (OpenRouter) in librechat.yaml with titleConvo: true.
   Config for test:

# librechat.yaml
version: 1.2.8
endpoints:
  custom:
    - name: "OpenRouter"
      apiKey: "user_provided"
      baseURL: "https://openrouter.ai/api/v1"
      models:
        default:
          - "google/gemma-3n-e4b-it"
        fetch: false
      titleConvo: true
      titleModel: "google/gemma-3n-e4b-it"

2. Start a new conversation with the model from OpenRouter

3. Observe the "Title generation timeout" error and the "Error getting endpoint config" warning in the logs.

The Custom Endpoint Config loading does need to be fixed, but it fails anyway with gemma since it doesn't support structured output (which is what we use by default for titling). We will implement a "chat/completions" method, as well as giving more ability to customize here, soon.

I'm also facing the same issue. Is there a model that currently works for titling with OpenRouter? I tried a few, both with titleMethod: "completion" and titleMethod: "functions", but I always get the same [api/server/controllers/agents/client.js #titleConvo] Error getting endpoint config error.

The titling works despite this error, though, but it defaults to using the same model used for the chat itself (which of course is not always optimal).

Got the same issue, i've previously mentioned here : #8112
