Trying to set up a CI/CD pipeline that registers flows. It just repeats this

18:44:38.783 | INFO    | botocore.credentials - Found credentials in environment variables.

and eventually times out. I'm running the

py

file that has the Flow as a script, and have this at the end:

if __name__ == "__main__":
    for memory in [15360, 30720, 63398, 126899]:
        base_args = make_deployment_args(flow_name1, memory, user="matt")
        storage1 = S3Bucket.load(<name>)
        deployment1 = Deployment.build_from_flow(
            flow=nb_flow, storage=storage1, **base_args
        )
    memory2 = 14360
    base_args2 = make_deployment_args(flow_name2, memory2, user="matt")
    storage2 = S3Bucket.load(<name>)
    deployment1 = Deployment.build_from_flow(
        flow=nb_subflows, storage=storage2, **base_args2
    )

It works fine when I run it interactively, but not in CI/CD.
