librechat.yaml not used or openrouter config not recognized

[cboehme42]

I use the following librechat.yaml:

version: 1.2.1

cache: true

interface:
  customWelcome: 'Welcome to LibreChat! Enjoy your experience.'
  fileSearch: true
  privacyPolicy:
    externalUrl: 'https://librechat.ai/privacy-policy'
    openNewTab: true

  endpointsMenu: true
  modelSelect: true
  parameters: true
  sidePanel: true
  presets: true
  prompts: true
  bookmarks: true
  multiConvo: true
  agents: true
  peoplePicker:
    users: true
    groups: true
    roles: true
  marketplace:
      use: false
  fileCitations: true

endpoints:
    - name: 'OpenRouter'
      apiKey: '${OPENROUTER_KEY}'
      baseURL: 'https://openrouter.ai/api/v1'
      models:
        default: ['deepseek/deepseek-r1-0528:free']
        fetch: true
      titleConvo: true
      titleModel: 'current_model'
      modelDisplayLabel: 'OpenRouter'

And docker-compose.override.yml:

services:

  api:
    volumes:
    - type: bind
      source: ./librechat.yaml
      target: /app/librechat.yaml

(both checked with validator and comments stripped).

LibreChat starts up, logfiles are empty, but openrouter is not showing up in the provider list and the welcome page uses a German standard greeting. I assume librechat.yaml is not read?

Error messages in the console:

Uncaught (in promise) non-precached-url: non-precached-url :: [{"url":"index.html"}]

Failed to load resource: the server responded with a status of 500 (Internal Server Error)

The error is "unauthorized".

I'd be very happy about hints how to debug or solve this...

Restarted from scratch, now it works. Still wished there was more debug info, but you can't have everything.
