Hi Everyone! I am starting some migration to prefect 2.0 and I'm facing some issues with blocks registering. Working on: - prefect 2.0.2 Steps: ## Server side - prefect orion start --host HOST --port PORT - prefect config set PREFECT_API_URL=httpHOSTPORT - prefect config set PREFECT_ORION_UI_API_URL=httpHOSTPORT (this taken from another thread here, otherwise the UI was showing blank pages for every option) ## User side - prefect config set PREFECT_API_URL=httpHOSTPORT At this point all semmed OK. If I try to register (from the user side) a block for using the CLI - prefect block register --file blocks/docker-block.py The messages are: - RuntimeWarning: coroutine 'Block.save' was never awaited - Successfully registered 1 block And the UI does not reflect the block. (docker-block.py)

from prefect.infrastructure.docker import DockerContainer, ImagePullPolicy

docker_block = DockerContainer(image="some-image",
image_pull_policy=ImagePullPolicy.ALWAYS,env=dict(PREFECT_LOGGING_LEVEL="DEBUG"))
docker_block.save("docker-image")

However if I add the block from the UI the change is reflected and shown. Any advice?

The same for me!

Thank you for bringing this to our attention! We've found the cause of this issue, and are currently working on a fix. It should be working again soon!

Thank you @Josh Furlin for the comment. I'll wait for the fix. In the mean time, any workaround for a docker pull issue? We have some gitlab registry for docker images: • my-registryPORT/image nametag-image when i try to run a flow in that image , its OK if the image is already downloaded, however if i try to run on a remote server (so an image pulling is required) an error is returned: • docker.errors.APIError: 400 Client Error for http+docker (other things) Bad Request ("invalid tag format") After checking it seems related to the double semicolon scheme.

This issue is known, and will be fixed in the next version, which should be our within the next few days.

Hi @Josh Furlin! I am testing prefect 2.0.3 and the block registering issue seems to be solved! thanks!

No problem!
