This would fix the issue but this is a little misleading IMO. If endpoint is null and this method returns true, it does not mean we canUseDirectPathWithUniverseDomain, but rather we can not validate it.
Can we not log direct path misconfigure on client initialization? And only adding endpoint.contains(Credentials.GOOGLE_DEFAULT_UNIVERSE) in channel creation where endpoint is guaranteed not null? This should be good enough to meet the requirement for universeDomain validation with DirectPath.

Makes sense. I think I can just remove the call from logDirectPathMisconfig() instead of trying to force it in there.
And only adding endpoint.contains(Credentials.GOOGLE_DEFAULT_UNIVERSE) in channel creation where endpoint is guaranteed not null? This should be good enough to meet the requirement for TPC.
sg, will update.

Kept this log statement as it only triggers if these three conditions above are true:
Might be beneficial since the user is has all the other DirectPath configurations correct except for Universe Domain.

It could be beneficial, but this check is called on every channel resizing, which by default is every minute, hence could cause spam logs to customers. That's why the logDirectPathMisconfigure was moved to the constructor initially, so I think we can skip this logging for now.

I see. Will remove then
