Ran into this bug earlier. The UI tells me to use the flag

--work-queue

but the CLI says no such option exists. Removing the

--work-queue

flagged resolved the issue.

Did you upgrade to 2.1.1 or are you still on an earlier version? I'm starting my agents with --work-queue now.

What version of prefect are you using?

--work-queue

flag seems to work okay for me on 2.1.1

Ah I see I ran prefect-aws -U and it left me on 2.0.4

Gotcha. Do a

pip install  -U prefect

to upgrade the core library. prefect-aws is the collection that gives some extra AWS-related block functionality.

if you install/upgrade Prefect first, and then you install a collection, Collection won't enforce any specific version
