hi everyone! i was trying to create deployment which is supposed to run on workpools using worker i want the code to be pulled from aws s3 .. created a deployment yaml for the same but getting Attribute error (nonetype has no attribute name) this is what the yaml looks like

# configuration for deploying your flows. We recommend committing this file to source
# control along with your flow code.

# Generic metadata about this project
name: activities-split-sync
prefect-version: 2.13.3

# build section allows you to manage and build docker images
build: null

# push section allows you to manage if and how this project is uploaded to remote locations
push:
- prefect_aws.deployments.steps.push_to_s3:
    id: push_code
    requires: prefect-aws>=0.3.4
    bucket: prod-prefect-s3-block
    folder: prefect
    credentials: "{{ prefect.blocks.aws-credentials.s3cred }}"

# pull section allows you to provide instructions for cloning this project in remote locations
pull:
- prefect_aws.deployments.steps.pull_from_s3:
    id: pull_code
    requires: prefect-aws>=0.3.4
    bucket: '{{ push_code.bucket }}'
    folder: '{{ push_code.folder }}'
    credentials: "{{ prefect.blocks.aws-credentials.s3cred }}"

# the deployments section allows you to provide configuration for deploying flows
deployments:

Hi Deepanshu, thanks for sharing your yaml. FWIW, everything looks fine to me so far. I've compared it to a yaml I used to pull/push code to s3 as well. The only difference I'm noticing is the double quotes around the reference to your credentials block

tried with single quotes.. still the same error

'prefect.yaml' did not conform to deployment spec: AttributeError("'NoneType' object has no attribute 'name'")

hmm..just to confirm, what CLI commands are you using to build the prefect.yaml and deploy?

prefect deployment apply prefect.yaml

prefect deployment apply prefect.yaml

Ah, I think that may be the problem

but how will this use the prefect.yaml

if you run this CLI command when you're inside the working directory where your prefect.yaml is stored, it will identify the deployment declaration in the prefect.yaml which matches the name you provide in the command, and then deploy the flow

thanks ! was able to deploy with this but getting an error

Flow could not be retrieved from deployment.
