YAML Parser error on Azure DevOps Pipeline-CodePudding

I'm getting the following error on my azure devop pipeline, it seems to relate towards parameters loop but despite writing the script multiple different ways I can't seem to get rid of it. YAML validators and my YAML linter don't detect an issue.

/azure-pipelines.yml (Line: 1, Col: 12): Unexpected value ''

Below is my code, it uses a template as well, which I will include beneath it.

azure-pipelines.yml

parameters:
steps:
- ${{ each project in parameters.projects }}:
  - task: UsePythonVersion@0
    displayName: 'Setting python version to 3.7'
    inputs:
      versionSpec: '3.7'
      architecture: 'x64'

  - task: PublishBuildArtifacts@1
    inputs:

If I throw your azure-pipelines.yml into the pipeline editor in Azure DevOps, it marks the line ending of parameters: with the warning

"Incorrect type. Expected "array"."

I didn't work with templates on pipelines so far, but from the MS doc page, it seems that you need to specify the parameters that you are passing like so:

#azure-pipelines.yml

parameters:
- name: projects
  type: object #object, since you are passing a list of strings
steps:
- ${{ each project in parameters.projects }}:
#...

It's suggested that you could enable the feature of YAML template editor with picture below and process the test. preview features Yaml template editor
