Hi All, I am trying to apply Authentication in flyte by following this article https://docs.flyte.org/en/latest/deployment/configuration/auth_setup.html Also used this article to solve "securecookie value too long " error. https://github.com/flyteorg/flyte/pull/4863/files and this securecookie value too long error is solved. But now a new error came up which is "Error reading secure cookie flyte_idt securecookie: base64 decode failed - caused by: illegal base64 data at input byte 10". {"json":{"src":"entrypoint.go:96"},"level":"info","msg":"Failed to create MutatingWebhookConfiguration. Will attempt to update. Error: mutatingwebhookconfigurations.admissionregistration.k8s.io \"flyte-binary-webhook\" already exists","ts":"2024-02-20T131627Z"} {"json":{"src":"cookie.go:106","x-request-id":"7ad600c65f77a6ea6122172fa0ae240b"},"level":"error","msg":"Error reading secure cookie flyte_idt securecookie: base64 decode failed - caused by: illegal base64 data at input byte 10","ts":"2024-02-20T131718Z"} {"json":{"src":"cookie.go:87","x-request-id":"7ad600c65f77a6ea6122172fa0ae240b"},"level":"error","msg":"Error reading existing secure cookie [flyte_idt].

Can you guys please help me out. Thank you. This error is also there! {"json":{"src":"token.go:80"},"level":"debug","msg":"Could not retrieve bearer token from metadata rpc error: code = Unauthenticated desc = Request unauthenticated with Bearer","ts":"2024-02-20T131718Z"} {"json":{"src":"handlers.go:303"},"level":"info","msg":"Failed to parse Access Token from context.

@Devendra Johari did you uninstall Flyte and then re-install at some point? I'm curious about this message:

Error: <http://mutatingwebhookconfigurations.admissionregistration.k8s.io|mutatingwebhookconfigurations.admissionregistration.k8s.io> \"flyte-binary-webhook\" already exists

given the byte error, this feels like an issue with the secure cookie too long handling

Yes it might be related to secure cookie length. I tried to use split token approach to solve that and do necessary changes in cookie.go and cookie_manager.go file. Although when i use latest flyte repo(without any change in go code) It shows Access denied error on login. While after doing changes as per the repository i included above. It is showing 401 Unauthorized with pod logs of securecookie base64 error. Can you suggest like what changes should I do to get rid of this base64 error throws by ReadSecureCookie function in cookie.go file of flyteadmin folder.

@Ingo Kemmerzell is also facing the same issue

We both are working in the same team😅

if you don’t make any changes, isn’t the cookie too long?

@Devendra Johari is this still an issue in your environment?
