Azure Devops CI pipeline trigger for multi projects

Question

I have the following structure:

Test-A and Test-B projects were created on Azure DevOps. Test-A project's CI build pipeline will produce an artifact.

Test-B's pipeline uses the artifact produced by Test-A's CI pipeline in its build. I am not able to  unable to do a CI automatic trigger with project Test-A dependency in project Test-B.

Below is my .yml file.

trigger:
- master

pool:
  vmImage: 'ubuntu-latest'


resources:
  pipelines:
  - pipeline: JustAName
    project: Test-A
    source: Test-A_CI
    branch: master
    trigger: 
      branches:
        include: 
        - master

  repositories:
  - repository: justAnotherName
    type: github
    name: myGitRepo
    endpoint: myGitServiceConnection   
    trigger:    
      branches:  
        include:  
        - master

steps:

- task: DownloadPipelineArtifact@2
  inputs:
    buildType: 'specific'
    project: 'hashValue or Test-A'
    definition: '1'
    specificBuildWithTriggering: true
    buildVersionToDownload: 'latest'
    targetPath: '$(Agent.BuildDirectory)'

 Is it a permission issue? what is the best way to check what is the problem and resolve the issue?
