Updating Instructions (docker):

# Linux command to Remove all existing images
docker images -a | grep "librechat" | awk '{print $3}' | xargs docker rmi

# Windows Powershell
docker images -a | findstr "librechat" | ForEach-Object { docker rmi $_.Split()[2] }

Then follow the directions here: https://www.librechat.ai/docs/local/docker#update-librechat

It works for me, here's my example azure config

endpoints:
  azureOpenAI:
    streamRate: 35
    titleModel: "gpt-4o"
    titleConvo: true
    groups:
    - group: "eastus"
      apiKey: "${EASTUS_API_KEY}"
      instanceName: "example-eastus"
      version: "2024-02-15-preview"
      models:
        gpt-4o:
          deploymentName: gpt-4o
    - group: "region-eastus"
      apiKey: "${EASTUS2_API_KEY}"
      instanceName: "example-eastus2"
      version: "2024-12-01-preview"
      models:
        gpt-4o-latest:
          deploymentName: "gpt-4o-mini"
          version: "2024-02-15-preview"
        o1-mini:
          deploymentName: "o1-mini"
        o1-preview:
          deploymentName: "o1-preview"
        o3-mini:
          deploymentName: "o3-mini"
    - group: "o4-mini"
      apiKey: "${O4_API_KEY}"
      instanceName: "example-eastus2"
      version: "2025-03-01-preview"
      deploymentName: "o4-mini"
      models:
        o4-mini: true

you can use the example they give in your deployment page as a reference for these values

No, still the same issue with v0.7.7 even I copied the exact same azure config. Naturally I replaced the variable names to match mine. I use Azure location: swedencentral.

Anyway, I can wait for the next release.

[danny-avila]

In that case, you need to wait for the next release if you are using the v0.7.7 tag, there's no way to make it work at that version.

Thank you for the fast reply! Same as OP, I continue to have the same issue, but I'll do the same as them - I'll wait for the next release :)

All good with v0.7.8
