I am getting a NullPointerexception when i filter and search the assignee users using firstName / LastName / Email.
The reason is that I haven't provided any email / LastName for the user, instead, i just created a user just with the userName. So matchesLike in KeycloakServiceBase is not handling this null case.

Camunda Version - 7.15
keycloak - camunda version - 2.2.0

Find below the stacktrace.

@shibin-aot: thanks for the bug report. I'm going to write a test case for this and try to reproduce it. A NullPointer should not never happen. Even if this is a rare edge case the Identity Provider should handle that accordingly. I'll let you know the results.

Sure @VonDerBeck Thanks for the quick response.
org.camunda.bpm.extension.keycloak.KeycloakServiceBase

  Line Num : 177
protected boolean matchesLike(String queryParameter, String attribute) {
	return queryParameter == null || (attribute != null && attribute.matches(queryParameter.replaceAll("[%\\*]", ".*")));
}

  This should avoid the nullpointer exception
