Hi all, I started testing my upgrade to 2.0 and downloaded the new version. I need to deploy an update to my 1.0 version which is still in prod and now I am getting an error with my tasks. How do I revert to the Prefect 1.0 version?

Hey @Madison Schott I think the simplest way would probably be to just setup a separate virtual environment for prefect 1 and prefect 2, the two versions of prefect are completely separate including the Cloud offerings for both of them so it's generally best to keep the two environments as separate as possible.

Makes sense, I think the damage is already done at this point though. How would I revert back?

Do you mean in terms of your code or just the prefect package itself? if it's just the package then you should be able to unintall prefect and then install the prefect version you need for your prefect 1 flows

yeah the package itself

the latest version of 1.0 is version 1.4.0

Ok I did that now I am getting this error:

if you run this command in the CLI does it show your cloud 1 tenants?

prefect auth list-tenants

yup

Brilliant, what ended up being the issue if you don't mind my asking?

Actually, false alarm...

Maybe but that would be odd since this should be based on the python version you have pointed for the image in your Dockerfile

Is it because of this

FROM prefecthq/prefect:latest

in my base image?

That'd do it, you'll need to use the base image that corresponds to your python and perfect version for the flow

Can you send me the link to where to find these again?

Yep I think you'll want this one https://hub.docker.com/layers/prefecthq/prefect/1.4.0-python3.9/images/sha256-adf068ab9e87bb543f8e67c2aa069eb89d55190a9dd92e46f9c14870f32d4ccf?context=explore

That did the job, thanks!

No problem 😄

Now I'm running the new flow and getting this error when running

dbt deps
