Hi Chris I think this is a Windows pathname issue we are currently working to fix If you run the deployment CLI command without the ` a` and then open the YAML file it generates do you see backslashes instead of forward slashes in the script path If so try changing them to forward slashes and then run `prefect deployment apply lt your deployment file gt yaml`

< Ryan Peden> Just to confirm it is retrieving the code from S3 right

Ryan Peden · Answer

Right it should only look for code in the Docker image if the <https github com PrefectHQ prefect blob b7758833c2a87dcb58f64a95c79bff4bb02fc5ff src prefect deployments py L710|deployment has no storage block>

Error

Chris Gunderson · Answer

I changed the yaml to get it to work

Ryan Peden · Answer

Thanks for the update I think we could do more to document how to map parameters from the YAML through to Python so I ll add it to our content roadmap
