Azure Data Factory构建管道ARM模板部署报错及后续问题求助

我正在执行一个基于ARM模板的Azure Data Factory构建部署管道，对应的YAML脚本如下：

# Starter pipeline
# Start with a minimal pipeline that you can customize to build and deploy your code.
# Add steps that build, run tests, deploy, and more:
# https://aka.ms/yaml

trigger:
- adf_publish

pool:
  vmImage: ubuntu-latest
steps:
- script: |
    tree $(System.DefaultWorkingDirectory)
  displayName: Show file structure of System.DefaultWorkingDirectory during a build


- task: AzurePowerShell@5
  inputs:
    azureSubscription: 'NewAzureConnection'
    ScriptType: 'FilePath'
    ScriptPath: '$(System.DefaultWorkingDirectory)/adf-xxxxx-xxxxx-dev/PrePostDeploymentScript.ps1'
    ScriptArguments: '-armTemplate "$(System.DefaultWorkingDirectory)/adf-xxxx-xxxx-dev/ARMTemplateForFactory.json" -ResourceGroupName $(ResourceGroupUAT) -DataFactoryName $(DataFactoryUAT) -predeployment $true -deleteDeployment $false'
    azurePowerShellVersion: 'LatestVersion'

- task: AzureResourceManagerTemplateDeployment@3
  inputs:
    deploymentScope: 'Resource Group'
    azureResourceManagerConnection: 'NewAzureConnection'
    subscriptionId: 'xxxxxx-xxxx-xxx-xxxxxxxx03'
    action: 'Create Or Update Resource Group'
    resourceGroupName: '$(ResourceGroupUAT)'
    location: '$(Location)'
    templateLocation: 'Linked artifact'
    csmFile: '$(System.DefaultWorkingDirectory)/adf-xxxxabric-dev/ARMTemplateForFactory.json'
    csmParametersFile: '$(System.DefaultWorkingDirectory)/adf-xxxxxx-dev/ARMTemplateParametersForFactory.json'
    overrideParameters: '-factoryName $(DataFactoryUAT)'
    deploymentMode: 'Incremental'

首次运行管道时，AzureResourceManagerTemplateDeployment@3任务失败，报错信息：

##[error]Failed to check the resource group status. Error: {"statusCode":403}

为订阅添加了Data Factory Contributor角色后，原403问题已解决，但现在出现了新的报错（对应截图），请问是什么原因导致的？
