Hi all, I’m not sure where the best place to post this is (here versus discourse), but I am running into an error when trying to register a prefect flow:

AttributeError: module 'lib' has no attribute 'X509_V_FLAG_CB_ISSUER_CHECK'

- it seems to be happening during this step

RUN pip install pip --upgrade

- has anyone come across this before and know how to fix it? I was able to successfully register this flow a few days ago and haven’t changed much in the requirements since then.

I think uninstall prefect and re-install it and see if that helps?

hmm do i need to reinstall it in the image or in my conda environment that I am using to register the flow?

If this is a registration issue, I think just on the registration environment. I think something weird happened with the package versions there

in the image my flow is stored in it is 37.0.0, in my conda env it is 36.0.0

I think that mismatch might be an issue? I don’t know for sure. It’s a really weird error 😅. For reference though, my stuff is working with 36.0.2 and Prefect 1.2

ok we are using 0.15.5

Ah ok. It might not even be cryptography

yeah i can rebuild the conda env

Maybe that might help. It’s not just cryptography tho one sec let me show you what i was reading

ohh haha weird. will check it out, thanks!

Oh maybe. Glad you found a working version though

me too 😅

Thanks @Anna Geller! For future reference, do you guys prefer we post these types of questions here or on discourse? Also as an updated, I did try a build where I upgraded the prefect version to

1.2

and I still got the same error, so I don’t think it has anything to do with the prefect version. I’ll continue pinning to cryptography version 2.8 for now.

it's totally up to you, I personally prefer Discourse because it supports syntax highlighting, quoting and is google searchable, but Slack is better for ad hoc quick questions - we support both equally Given we are already talking about this on Discourse, let's continue there about this issue, but overall both are fine

Good to know, thanks Anna!
