Open WebUI 0.9.6 still initializes its embedding function during startup, even when OFFLINE_MODE=true and BYPASS_EMBEDDING_AND_RETRIEVAL=true. With OFFLINE_MODE=true and no cached SentenceTransformer model, startup failed with:
ValueError: No embedding model is loaded. Set RAG_EMBEDDING_MODEL to a valid SentenceTransformer model name, or configure an external RAG_EMBEDDING_ENGINE (ollama, openai, azure_openai).
Configure the tests to use a dummy Ollama embedding endpoint so startup does not try to load or download a local embedding model. The endpoint is not meant to be contacted by these tests; it only keeps startup on the external embedding configuration path.
Open WebUI redirects from /auth to / after OIDC login and briefly shows the "You're now logged in" toast during that transition. The toast is not a stable post-login signal, so the VM test can fail even though SSO succeeded.
Wait for the final root URL and verify the authenticated Open WebUI session through /api/v1/auths/ instead. This keeps the test focused on the expected SSO outcome while avoiding the transient UI race.
