Yaml number type not being recognised as a integer

Got a little problem which I am sure a Yaml guru will quickly solve for me.

We have a set of parameters thus on a Azure pipeline Yaml file

parameters:
  - name: customers
    type: object
    default:
      - name: module
        type: string
        default: Warmup
      - name: timeout
        type: number
        default: 20

      - name: module
        type: string
        default: Sidebar
      - name: timeout
        type: number
        default: 15

and so on, further down the yaml file we have a loop

- ${{ each section in parameters.customers }}:
  - task: VSTest@3
    displayName: 'Testing - ${{ section.module }} '
    inputs:
      testAssemblyVer2: 'C:\Code\Release\net7.0\CodeRegression.dll'
      searchFolder: 'C:\Code\Release\net7.0\'
      testFiltercriteria: 'TestCategory=${{ section.name }}'
      testRunTitle: 'Regression ${{ section.name }}'
      platform: '$(buildPlatform)'
      configuration: '$(buildConfiguration)'
    continueOnError: true
    condition: succeededOrFailed()
    timeoutInMinutes: ${{ section.timeout }}

But I get an error

And validate shows this

Any thoughts on where I am going wrong please?

Please note there's no such thing as schemas for the Azure pipelines parameters. You can define a parameter as object, but there's no way to enforce a specific structure and types for each property.

Instead of:

parameters:
  - name: customers
    type: object
    default:
      - name: module        
        type: string
        default: Warmup
      - name: timeout       
        type: number
        default: 20

      - name: module        
        type: string
        default: Sidebar
      - name: timeout       
        type: number
        default: 15

You can define an array with 2 elements like this:

parameters:
  - name: customers
    type: object
    default:
      - module: Warmup
        timeout: 20

      - module: Sidebar
        timeout: 15

I'm not completely sure if only 2 properties (module and timeout) are required in your specific scenario for each element, but obviously more can be added if required.

Using parameters.customers:

- ${{ each section in parameters.customers }}:
  - task: VSTest@3
    displayName: 'Testing - ${{ section.module }} '
    inputs:
      testAssemblyVer2: 'C:\Code\Release\net7.0\CodeRegression.dll'
      searchFolder: 'C:\Code\Release\net7.0\'
      testFiltercriteria: 'TestCategory=${{ section.module }}'
      testRunTitle: 'Regression ${{ section.module }}'
      platform: '$(buildPlatform)'
      configuration: '$(buildConfiguration)'
    continueOnError: true
    condition: succeededOrFailed()
    timeoutInMinutes: ${{ section.timeout }}
