通过REST API跨项目传参调用Pipeline遇500错误求助

我尝试通过REST API，使用System.AccessToken将参数传递给跨项目的Pipeline，具体配置如下：

Project A: deploy.yml #

parameters: 
  - name: testparam
    type: string
    default: "default"
    
steps:
  - script: echo hi

Project B: pipeline.yml #

jobs:
- job: CallDeploymentPipeline
  pool: Server    
  steps:  
  - task: InvokeRESTAPI@1
    displayName: Call different-project Pipeline
    inputs:
      connectionType: 'connectedServiceName'
      serviceConnection: "myGenericServiceConnectionName"
      method: 'POST'
      headers: '{ "Authorization":"Bearer $(System.AccessToken)", "Content-Type":"application/json" }'
      body: '{
        "resources": { "repositories": { "self": { "refName": "$(Build.SourceBranch)" } } },
        "templateParameters": { "testparam": "test" }
      }'
      urlSuffix: '/ProjectA/_apis/pipelines/<deploy pipeline ID>/runs?api-version=7.1'
      waitForCompletion: 'false'

执行错误信息 #

Response: An error was encountered while processing request. Exception: {"$id":"1","innerException":null,"message":"The repository RepoA in project could not be retrieved. Verify the name and credentials being used.","typeName":"Microsoft.TeamFoundation.DistributedTask.Pipelines.ResourceValidationException, Microsoft.TeamFoundation.DistributedTask.WebApi","typeKey":"ResourceValidationException","errorCode":0,"eventId":3000}
Exception Message: The remote server returned an error: (500) Internal Server Error. (type WebException)

可正常运行的修改方案 #

以下任一修改均可让Pipeline正常运行：

• 移除"templateParameters": { "testparam": "test" }行，不传递参数
• 使用PAT替代System.AccessToken
• 将两个Pipeline迁移至同一项目中

已完成的权限配置 #

已将组织和项目层级的“限制非发布管道的作业授权范围为当前项目”设置为OFF，且Project Collection Build Service账号已拥有RepoA的读取权限和Project A中部署Pipeline的队列构建权限。

疑问 #

按照Run Pipeline API文档操作，请问当前操作是否存在错误，还是这是一个已知bug？
