Template error in YAML Pipeline - Azure DevOps

I am trying to build reusable pipeline and basic architecure is -

I have multiple application repositories (appRepo1, appRepo2,..) and all of them having their yaml pipeline for example (appRepo1.yml, appRepo2.yml,..)

These app pipelines will call common pipeline(common.yml) which is in different repository (CommonRepo).

The common pipeline(common.yml) will be responsible to call other template pipeline(Scanning.yml in ScanRepo,Infra.yml in InfraRepo ) which are in different repositories.

Basically I want to keep application's pipeline YAML to be very thin

. I don't want to call different templates of different repository from application pipeline. Instead Common template yaml of common repository should templates from various repository.

appRepo.yml

   name: "$(BuildDefinitionName)_$(SourceBranchName)_$(date:yyyyMMdd)$(rev:.r)"

trigger: none
resources:
  repositories: 
  -  repository: CommonPipeline
     type: GIT
     name: CommonPipeline
     ref: "dev"
  
extends:
 template: common.yml@CommonPipeline

common.yml in CommonRepo

resources:
  repositories: 
    - repository: InfraRepo
      type: GIT
      name: "InfraRepo"
      ref: "dev"
    - repository: ScanRepo
      type: GIT
      name: "ScanRepo"
      ref: "dev"


variables:
        - template: Pipeline/vars/app-var.yaml

stages:
        - template: Pipeline/stages/scanning.yml@ScanRepo
        - template: Pipeline/stages/infra.yml@InfraRepo

Is it possible to put (resources -> repositories) in both appRepo.yml and common.yml ? I am getting an error when I run appRepo1 pipeline(appRepo.yml) if i keep resources section in common.yml.

Error is -

Internal error reading the template. Expected a scalar,a sequence,or a mapping

No, it's not possible to have resources > repositories in both root and template YAML due to the YAML schema limitations in Azure Pipelines. This would cause a duplication of the resources section within the compiled YAML pipeline which is not valid.

So, you would need to add the repositories in the appRepo.yml template. If you are worried about exploitation of the templates, you can check Security through templates

Also check out how you can enhance pipeline security using resources
