Hey all! Can anybody help with a github storage block? When I run the flow, I keep getting the message 
Flow could not be retrieved from deployment
with a stack trace that leads to a 
NotImplementedError
. I have tried several variations on the --path argument, tried a public repo instead of a private - nothing works! Please help! flow-code:

When you run your deployment command, the 
<path-to-flow.py:flow-function>
should be relative to the root of the repository. If your current directory is the root of the repo, and 
src
is a folder in that root, deploy with
Copy code
prefect deployment build src/log_flow.py:log_flow -n log-simple-test -q test -sb github-repository/test-public-repo --apply
the path in your deployment yaml is
Copy code
path: /Users/zachloertscher/test-public-github-repo
whereas the path in my deployment yaml is
Copy code
path: ''
which leads to this log

Thanks, @Kevin Grismore! The error persists though, unfortunately: deployment command:

Does running asyncio on windows cause any issues like this
k
Sorry, I haven't tried that myself
z
Have you had success with github-repository storage bocks in the past?
k
I've been using both gitlab and bitbucket repo blocks
Based on the logs it looks like you're running the agent locally on windows?
z
Yes it's just a locally run agent on windows
k
I did find this based on the error which seems to be about running 
asyncio
on Windows: https://stackoverflow.com/questions/44633458/why-am-i-getting-notimplementederror-with-async-and-await-on-windows
z
Maybe I'll give it a try with 
wsl
- thanks again for your help!
k
np!

gratitude thank you 1

Just to circle back on this - in case anybody is wondering, I tried running my prefect agent on WSL (windows subsystem for linux) and it worked fine Would be awesome to have agents working on local windows machines for github-repo storage blocks!

Hey Zachary, I appreciate you sharing the solution that you discovered. Just out of curiosity, do you have prefect-dask installed in your exection environment? We've previously seen the 
NotImplementedErrror
thrown when that package was installed.
z
Hi Bianca - yeah I did prefect-dask installed in my environment
b
Ahh I see. That may have contributed to the error message then.
z
Yes - I believe so! I went ahead and ran 
pip uninstall prefect-dask
to try it on Windows again, but it threw a FileNotFound error (& still works on WSL). Should I submit a github issue?:
