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 :

Answer 1

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.

Answer 2

the real problem is keycloak has 21 major versions and it works differently in each one. the documentation, however, does not aknowledge that and doesn't help a bit with setting up your integration with keycloak.

i had the exact same problem as this question and ended up fixing it watching a tutorial on youtube(link bellow).

so yeah, this is A solution to this problem, maybe not the best, but works fine. problably will be different in another version of keycloak but, as of version 21.1.1 this works well. Personaly, i wouldnt use keycloak ever again, i followed the documentation and spent hours trying to make it work just to throw all the knowledge i got from the official docs off the window and follow a tutorial. for example, the docs say that the redirect uri is required for the token request but, i didnt need it at the end. Anyways, I hope this helps anyone in need.

Your comment does not help to solve the problem, since a redirect_uri is needed as the author mentioned. – Likewise

like i said, i know that it should be needed, but i tried multiple times and couldn't get it to work, the tutorial helped me fix it, maybe if you watch, it can help you. I dont really understand it, but seems like you can just set the redirect uri in the keycloak server configs(just follow the tutorial) and it redirects correctly after logging in @Likewise – Solvency

i know it is counter-intuitive to abandon the docs and just do what some stranger says in a poor quality video, but it worked for me and thats good enough. after wasting days reading the docs to no avail, anything goes – Solvency

Answer 3

I was stuck on this same issue, and finally found this in the openid-connect-core documentation:

3.1.3.2.  Token Request Validation
    The Authorization Server MUST validate the Token Request as follows:

        * Authenticate the Client if it was issued Client Credentials or if it uses another Client Authentication method, per Section 9.
        * Ensure the Authorization Code was issued to the authenticated Client.
        * Verify that the Authorization Code is valid.
        * If possible, verify that the Authorization Code has not been previously used.
        * Ensure that the redirect_uri parameter value is identical to the redirect_uri parameter value that was included in the initial Authorization Request. If the redirect_uri parameter value is not present when there is only one registered redirect_uri value, the Authorization Server MAY return an error (since the Client should have included the parameter) or MAY proceed without an error (since OAuth 2.0 permits the parameter to be omitted in this case).
        * Verify that the Authorization Code used was issued in response to an OpenID Connect Authentication Request (so that an ID Token will be returned from the Token Endpoint).

This solved the issue for me since I wasn't using the identical uri as the initial Authorization Request.
