Issue with Keycloak Benchmark 0.15-SNAPSHOT API Load Test

[Arif EROL]

Hello,

I am attempting to perform a load test using the Keycloak Benchmark 0.15-SNAPSHOT API with Keycloak version 26.0.5, using the CLI command below. However, I am encountering the error:
"regex(action="([^"]*)").find.transform.exists, found nothing"

Could you please help me understand what might be the cause of this error and how I can resolve it?

Here is the load test CLI command I'm using:

bin/kcb.sh \ --scenario=keycloak.scenario.authentication.LoginUserPassword \ --server-url=https://serverdnsname.com/ \ --realm-name=77333955-7fbd-3801-ca61-d3f7df1df65z \ --username=username \ --user-password=password \ --client-id=63a15c87-c553-4977-b39b-396d96d3eda7 \ --client-secret=9YP7502dFcHrKgTBBcTqXuoBtbsCknAC \ --client-redirect-uri=https://redirect-uri.com/signin-oidc \ --users-per-sec=1 \ --concurrent-users=15 \ --measurement=10 \ --log-http-on-failure

Looking forward to your guidance.

Thank you!
