@squakez I think the test failure is happening because I did not commit the updated CRDs ? am I thinking correctly here ?
I am also working on the caCert trait option for trusted root certificates issue. do we have to commit the CRDs that we locally generate ?

Yes. If any change in the crds, make generate is required.
