User profile error

[javshak]

Hi - I have used the library for a Flutter web app I am building however I get the following error twice (details below).

Error: Exception: The user profile was not loaded as the user is not logged in.

I have used the main.dart file from the example you have provided - modified just the credentials. When my page loads I get the above error. Then on clicking the Login button I am redirected to the Keycloak server and after a successful login I am sent back to my app however this error shows up again.
Any advice?

Hi, can you provide minimal reproducible code so that I can look into it

Hi, can you provide minimal reproducible code so that I can look into it

Hey thanks for the reply! Regarding the code I have replicated the code from your 'example' project except for the following changes in the main.dart file ( Provider -> create () ).
No additional changes besides some text labels. I also downloaded your code (example) from github and ran it. I get the same error (posted previously) with no changes made when the main.dart is loaded.

            var keycloakService = KeycloakService(KeycloakConfig(
                url: 'https://ctisaas.com:9091/auth/', // Keycloak auth base url
                realm: 'master',
                clientId: 'jst'));
            keycloakService.keycloakEventsStream.listen((event) {
              if (event.type == KeycloakEventType.onAuthSuccess) {
                  print('the user is authenticated successfully!' );// User is authenticated
              }

I also see this error in the Chrome debug window -
Refused to frame 'https://ctisaas.com:9091/' because an ancestor violates the following Content Security Policy directive: "frame-ancestors 'self'". Not sure why this would be but looks like some issue related to cookies. In the Network tab I can see this -

Request URL: https://ctisaas.com:9091/auth/realms/master/protocol/openid-connect/3p-cookies/step1.html
Request Method: GET
Status Code: 404 
Remote Address: 13.248.163.143:9091
Referrer Policy: strict-origin-when-cross-origin

Not sure why it is trying to navigate the 'step1.html'.

Let me know if this is helpful.

I think I found my problem .....issue is in keycloak client settings. I changed my client access type to public then it worked . This issue pops up when client access type is confidential.

Hi @VenkatraghuB
I have used the same code and I am having having the issue as you mentioned before.

Keycloak Version 16.1.1
Flutter Version 2.10.3

Here is my error:

Uncaught (in promise) Error: Exception: The user profile was not loaded as the user is not logged in.

I have checked with AccessType as "public" also but no success.

Here is my Keycloak settings.

What am I missing here?

Hi,
Is there an update to the above mentioned issues? Even I'm facing problems while trying to loadUserProfile. If anyone can kindly post their solution here, that would be helpful. Thank you.

[VenkatraghuB]

This issue is mainly because of client settings in keycloak. Look out for following

1. AccessType shld be public
2. Redirect URIs shld be defined
3. WebOrigins: *
   That should do the trick
