Failing with 400 Bad Request

[DenuxPlays]

Current Behavior

When I try to import my realm.json I just get an error that keycloak returned 400.

Create method returned status Bad Request (Code: 400); expected status: Created (201)

Or

2025-02-05T13:01:58.449Z ERROR 1 --- [           main] d.a.k.config.KeycloakConfigRunner        : HTTP 400 Bad Request

Currently it is impossible to tell what is wrong and it could be anything.

Expected Behavior

Log keycloak response so that I can tell what is wrong.

Steps To Reproduce

1. Make invalid config (idk what exactly)
2. try to import using the cli

Environment

• Keycloak Version: 26.0.7
• keycloak-config-cli Version: 6.3.0
• Java Version: 21

Anything else?

No response

Hi @DenuxPlays, thank you for reporting this. Could you please update your Keycloak version to 26.1 and test again?

1. No. We Cannot just Update the Keycloak Version on our Server
2. it wont fix anything

The error was a wrongly escaped regex validator.
We've Managed to get the keycloak response by using tcpdump and analyzing the Network traffic.

Its just a request to Print the response from keycloak as it already would've told me what was wrong.

@DenuxPlays, my response was based on a similar issue with newly introduced attributes in recent Keycloak Realm Representations that have already been fixed.

If you've found a solution, then that's perfect! :)

so can this be closed?

No

This is not really a bug.

More like a "Hey if keycloak does not return a success http code just print the response from keycloak"
My issue is that we had to tcpdump the network traffic to discover this.

Where you log this:

2025-02-05T13:01:58.449Z ERROR 1 --- [           main] d.a.k.config.KeycloakConfigRunner        : HTTP 400 Bad Request

just add:

logger.error("Keycloak response: {}," response);

So that these kind of issues can be easily identified without needing to intercept the actual http traffic.

@DenuxPlays

I have added changes to log the Keycloak response when an error occurs. This will help identify issues without intercepting the network traffic, as you did. you can add a review #1271

thanks
