Keycloak Token request rejected because of invalid redirect URI

Question

After upgrading to Keycloak version 1.9.1 we’ve started to get rejections from keycloak.js while getting token based on code.

If we enter base url (http://example.com) then the app works fine, login is successful and token is retrieved.

Unfortunately when entering this child page (https://example.com/?redirect_fragment=/asset-library/card-view/ - it is sent from javascript with redirect_fragment encoded, but in keycloak logs it’s visible with this fragment decoded) we get error 400 while getting token after succesful login and obtaining the code. The precise response is:

{
  "error_description": "Incorrect redirect_uri",
  "error":"invalid_grant”
}

Why is that? In valid redirects uri in keycloak we have (just in case):

- https://example.com*
- https://example.com/*
- https://example.com/?redirect_fragment=/asset-library/card-view/
- https://example.com/?redirect_fragment=%2Fasset-library%2Fcard-view%2F
- http://example.com*
- http://example.com/*
- http://example.com/?redirect_fragment=/asset-library/card-view/
- http://example.com/?redirect_fragment=%2Fasset-library%2Fcard-view%2F

Here are the logs of succesful log in with redirect URI beeing http://example.com :

Solution

Seems like you are trying both https and http URL schemes. The Valid Redirect URIs settings is a regex pattern against which are the redirect URIs validated.

Anyway, you should keep entire page on the secured HTTP for security reasons. Thus a redirect pattern like: https://example.com/* should work.
