Title Generation Fails in v0.7.9-rc - "parse is not a function" Error

[ogipogi]

Bug Description

The titleConvo functionality that was working in version 0.7.8 now fails in version 0.7.9-rc and main branch with the error: this.client.chat.completions.parse is not a function

Steps to Reproduce

1. Configure LibreChat with the following config structure (see configuration below)
2. Enable titleConvo: true for Azure OpenAI endpoints
3. Start a conversation
4. Observe the error when the system attempts to generate a conversation title

Configuration Used

endpoints:
  agents:
    titleConvo: true
    titleModel: "gpt-4.1"
    plugins: true
  azureOpenAI:
    plugins: true
    groups:
      - group: "azure-deepseek"
        assistants: false
        displayTitle: "DeepSeek-R1"
        apiKey: "[REDACTED]"
        baseURL: "https://[REDACTED].services.ai.azure.com/models"
        version: "2024-05-01-preview"
        serverless: true
        dropParams: ["stop"]
        models:
          DeepSeek-R1: true
      - group: "azure-gpt4.1"
        assistants: false
        titleConvo: true
        displayTitle: "GPT-4.1"
        apiKey: "[REDACTED]"
        instanceName: "[REDACTED]"
        baseURL: "https://[REDACTED].openai.azure.com/openai/deployments"
        version: "2025-01-01-preview"
        models:
          gpt-4.1:
            deploymentName: "gpt-4.1"

Error Details

Error Message:

2025-07-16T12:38:57.535Z error: [api/server/controllers/agents/client.js #titleConvo] Error this.client.chat.completions.parse is not a function

Location: api/server/controllers/agents/client.js #titleConvo

Environment

• LibreChat Version: 0.7.9-rc (also reproduces on main branch #52bbac)
• Previously Working Version: 0.7.8
• Configuration: Azure OpenAI with custom groups and title generation

Expected Behavior

The system should generate conversation titles automatically when titleConvo: true is enabled, as it did in version 0.7.8.

Actual Behavior

The title generation fails with a function undefined error, suggesting that the parse method is not available on the client object.

I'm not able to reproduce it, and can use azure serverless models for titling conversations.

titleConvo is an endpoint-level config, too, not group-level:

https://www.librechat.ai/docs/configuration/azure#endpoint-level-configuration

For your GPT-4.1 config, try a non-serverless config like this (you don't need to include a baseURL:

endpoints:
  azureOpenAI:
    streamRate: 35
    titleModel: "gpt-4.1"
    titleConvo: true
    groups:
    - group: "region-eastus"
      apiKey: "${EASTUS2_API_KEY}"
      instanceName: "eastus2"
      version: "2024-12-01-preview"
      models:
        gpt-4.1:
          deploymentName: "gpt-4.1"
