Assertion error on host name when connecting to IBM queue

Question

I am trying to connect to IBM queue for my cucumber tests, but getting the below assertion error. If we bypass the assertion by running the via feature file or removing assertions from vm options, it works fine, configuration is for java 17.

java.lang.AssertionError

Any help would be appreciated. TIA.

Tried bypassing assertion in pom xml configuration and in command line mvn clean install. Still the assertion error persists.
