Receiving 'found nothing' error when using LoginUserPassword or AuthorizationCode scenarios.

Describe the bug

I have a Keycloak instance running in an EKS cluster with 2 replicas. I want to perform performance testing on user logins, so I used Keycloak's benchmark-module to conduct the tests. Below is the command I executed:

./bin/kcb.sh \
--scenario=keycloak.scenario.authentication.LoginUserPassword \
--server-url=<server-url> \
--realm-name=master \
--client-id=<client-id> \
--username=<user-name> \
--user-password=<user-password> \
--users-per-sec=1 \
--concurrent-users=5 \
--measurement=600 \
--log-http-on-failure

Upon execution, I encountered the following error:

13:27:30.283 [DEBUG] i.g.h.e.r.DefaultStatsProcessor - Request 'Browser to Log In Endpoint' failed for user 2: regex(action="([^"]*)").find.transform.exists, found nothing

I tried adjusting various configurations, but none resolved the issue; they all led to the same error. However, other scenarios like keycloak.scenario.authentication.ClientSecret and keycloak.scenario.admin.ListSessions work fine for me.

Since I faced this issue with Keycloak v23.0.6, I upgraded my Keycloak instance to v25.0.5 and used Keycloak Benchmark 0.13. Unfortunately, I still encounter the same error.

Version details:

Keycloak Benchmark Module: Keycloak Benchmark 0.13
Keycloak Version: 25.0.5

Version
