What is the correct way to start the agent using an API key? Previously this worked:

prefect agent local start --token [some-token] --api <https://api.prefect.io>

But after generating an api KEY (not a token) and running a similar incantation:

prefect agent local start --token [THE-NEW-KEY] --api <https://api.prefect.io>

it complains with

prefect.utilities.exceptions.ClientError: [{'path': ['register_agent'], 'message': 'Unauthorized: permission error.', 'extensions': {'code': 'FORBIDDEN'}}]

Token is deprecated. You’d want to make a new API key and then

prefect agent local start --key API_KEY

. But actually I think this should still work.

When using the incantation you suggested, it gives this error:

Error: no such option: --key

Ah ok. You are on a version below 0.15.0?

We're on 14.21 Do we need to upgrade?

Can you try the

--token

but also do the logout first and take out any keys/tokens in the

config.toml

?

When running this:

prefect auth logout

it complains:

Error: Auth commands with server are not currently supported.

Are you on server or cloud?

Cloud

Ah ok you can also do

prefect backend cloud

or

prefect backend server

to toggle. I think we should be good to try again

Found the issue... Our startup script was still calling

prefect backend server

even though we've been using cloud for months 🤷 The agent starts now using the

--token

argument with the newly generated KEY Thank you Kevin!

Ah lol. Glad you figured it out!
