Hi all, I'm trying out Prefect Orion (v2.0b3) and was following the orion tutorials. I am having issues updating an existing deployment, which the docs mentioned can be done by 
prefect deployment create
. Getting a 
prefect.exceptions.ObjectAlreadyExists
error. Is this expected?
k
I’ve only seen this happen when you do something like create a deployment to an Orion instance inside a container. Is that what you are doing?
And I couldn’t even properly replicate it. Could you tell me more about your setup?
m
I'm testing prefect in a conda env in virtualbox guest ubuntu 20.04 on a windows host machine. Basically created a deployment following this https://orion-docs.prefect.io/tutorials/deployments/, then changed the deployment spec parameters and rerun 
prefect deployment create
, which failed
k
Did you configure a storage?
m
Nope
The only prefect config I changed was setting 
PREFECT_ORION_API_HOST='0.0.0.0'
to allow my host to access the prefect UI on the browser, not sure if that affects this
k
Could you try resetting the database and seeing if that works?
You could also just try the Cloud 2.0 directly. It might be easier to use.

Still had the same issue after resetting, fails the second time I run 
prefect deployment create
Tried Cloud 2.0, same issue. Oh well. Attaching a screenshot here of the error tracebacks for reference (same error for both ephemeral and cloud)

Ok I don’t think there are any engineers I can ping right now but I’ll ask them tom

I am just going to bump that I have dug into the source code and have a feeling it's not handled with the intended logic in mind. I had the same problem and could exactly where it was happening with no error handling / try except despite the behavior clearly being that it should update the existing object on conflict.

For the team, here is the exact line of code / location where the logic as its described is not coded to do what it says. https://github.com/PrefectHQ/prefect/blob/66815a2a52783d0cd6fde7575859a886b1a10116/src/prefect/client.py#L856 Here is the API piece thats invoked so you can close the loop and see there is no handling to update the block as expected/desired. https://github.com/PrefectHQ/prefect/blob/orion/src/prefect/orion/api/blocks.py#L29 Hope this helps make it ez, I did the digging already 🙂

Will forward @Alexander Butler! Thank you for investigating
