Unable to Load Dashboard Page
Describe the bug
Che Dashboard crashes due to errors on the front end.
Che Dashboard redirects to keycloak, logs user in, and redirects back to che daskboard, here the user's token (/api/token) is valid and the user's (api/user) is also populated properly. These are the logs in the front end:
client.f26467f483f9ac419981.js:1 Skip keycloak settings field: che.oidc.auth_server_url client.f26467f483f9ac419981.js:1 Skip keycloak settings field: che.oidc.username_claim client.f26467f483f9ac419981.js:1 Skip keycloak settings field: che.oidc.oidc_provider
vendor.591bfce3d6abac540979.js:66 WebSocket connection to 'wss://code.url.com/api/websocket?token={token}' failed:

After that the websocket keeps trying to connect and failing.
Within my setup, I am using an external keycloak service.
Che version
7.42@latest
Steps to reproduce
- Deploy Che Helm Chart using ArgoCD
- Change Keycloak Url / Realm / Client to Custom Keycloak Information
- Add to the config map the url adapter:
CHE_KEYCLOAK_JS__ADAPTER__URL: {{ .Values.customOidcUrl }}/js/keycloak.js - Sync Che
- Go to Che Dashboard url, login, white screen.
Expected behavior
Dashboard to not show a white, empty screen.
Runtime
Kubernetes (vanilla)

I'm not sure about using keycloak with 7.42 version of Che.
Could someone clarify it.
maybe @tolusha...
Okay -- Is there a version I should be using to utilize keycloak? Thanks!
If you're running devworkspace mode, which I think is the default in Che 7.42 Kubernetes api Server requires to validate against Keycloak. We had similar issues with Che 7.42.
Since documentation is quite limited on the Kubernetes side I summarized what worked in our case. Maybe that helps.

At least in native auth mode keycloak works as expected. :)
I think 7.41 was the last version that deploys keycloak by default.
