Hi folks 👋, I tried to ask Marvin but it did not help in my case, so I will try to ask my question here. 👉 I am running the following command

prefect deployment build path-to-file/prefect_flows.py:simple_test --name simple_test_flow -sb github/my-cicd -t some_tags --apply

and I have an existing block on prefect cloud that can be easily accessed as follows

from prefect_github.repository import GitHubRepository

github_repository_block = GitHubRepository.load("my-cicd")

Why am i getting the following error:

ValueError: Unable to find block document named my-cicd for block type github

? Currently using the Prefect version: 2.19.7 - thanks 💡

hi @GiuxJua - this usually happens when you're mistakenly pointing at a workspace (or local ephemeral API) that doesnt have your block registered what does

prefect config view

show?

Hey @Nate thanks for the reply - it seems weird to me, since all the config (and secrets) point exactly to the right ones 😞 and the block is living in the right project. However, I found an interesting issue: • if we use the "old" github block class (that is gonna live until Sept 2024) then the flow is deployed and run successfully 🎉 • if we use the "new" github blocks then the error is raised. Any idea of where this is happening? Where should I rise this issue so that possiblyother people can be aware of?

when you used the "new" GitHub block, did you use the one from

prefect-github

? had you created a block named

my-cicd

of that type?

Hey @Nate yes - the new refers to the

prefect-github

library. If, instead, I use the deprecated way, everything works - it seems to me a bug.

can you show the entire stack trace?

@Nate here it is (ENV is just a fancy name to avoid sensitive info to be public)

ValueError: Unable to find block document named my-cicd for block type github

An exception occurred.

The strange thing is that

from prefect_github.repository import GitHubRepository

github_repository_block = GitHubRepository.load("my-cicd")

works from a python shell. However, under the deployment it raises this issue (which is then solved using the old way, i.e.

from prefect.filesystems import GitHub

hmm so if you do

prefect block ls | grep github-repository

you do have an entry for that specific block type? this > ValueError: Unable to find block document named my-cicd for block type github doesnt make sense to me if that is the case

Hey @Nate thanks for the reply - running your code gives me

sha_code │ GitHub Repository  │ my-cicd             │ github-repository/my-cicd

so the block exists, and lives in the right project. I therefore cannot understand why that is not working. The strange thing is that using the

prefect.flesysyem.GitHub

class works and this is something I cannot understand why. Any chance for a follow up? 🙏

>

hmm i bet you're right and this is a bug around the block type slug. because

github

should correspond to

prefect.filesystem.Github

, not

prefect_github.repository.GitHubRepository

can you please share the output of the following so I can look into this?

pip list | grep -E 'prefect|github'
