Hi @chingor13, I was diving into #8 and found your PR.

IIUC, the issue here is that the service account used to execute tests has Project Owner role granted.
I was able to pass tests locally when my service account is only granted Project Editor role. The reason is that Project Owner has serviceusage.services.use. This lets requests succeed without having the user set a user_project as expected.

An alternative solution to this is to create a new service account for this project that only has Project Editor role.

This was encountered here as well: googleapis/google-cloud-java#3448

Totally open to discussing this more. I don't know where the service account is stored but I can help update it with a new service account credentials file to unblock this failure.
