Is there a way to authenticate the client other than using prefect auth login? I am trying to use prefect inside a CI/CD pipeline and it would be ideal to set an environment variable instead.

Yep! You can create a

TENANT

token (https://docs.prefect.io/orchestration/concepts/tokens.html#tenant) and set it as

PREFECT__CLOUD__AUTH_TOKEN

.

I get this error when using a tenant token with the client (venv) (base) % prefect register flow -f scripts/example.py -p example -l 488335898155-default /usr/local/anaconda3/lib/python3.8/site-packages/prefect/core/flow.py1674 UserWarning: No result handler was specified on your Flow.

Ah, I see what's happening here. Add

no_url=True

to your

flow.register

call and things should work for now.

Thanks. That worked.
