amazon-web-services - CodeBuild 无权执行 : sts:AssumeRole on arn:aws:iam/. ..... InvalidInputException;为什么？

Question

我有一个 cloudformation 堆栈，它导出此角色并附加了一些策略:

      CodeBuildRole:
        Type: AWS::IAM::Role
        Properties:
          RoleName: codebuild-role
          AssumeRolePolicyDocument:
            Statement:
              - Action: ['sts:AssumeRole']
                Effect: Allow
                Principal:
                  Service:
                    - codebuild.amazonaws.com
                    - codepipeline.amazonaws.com
            Version: '2012-10-17'
          Path: /
          Policies:
            - etc....

导出的角色名称是cb-remove-role-id，然后我尝试将其导入到另一个堆栈中，以供代码管道中的另一个代码构建项目使用

      BuildProjectUK:
        Type: AWS::CodeBuild::Project
        Properties:
          Name: !Sub ${ResourceContext}-build-uk
          Description: UK build and deploy
          ServiceRole: !ImportValue cb-remove-role-id
          BadgeEnabled: false
          Artifacts:
            Type: CODEPIPELINE
          Environment:
            etc...

当尝试更新后一个堆栈的模板时，我收到此错误:

Failed to call UpdateProject, reason: CodeBuild is not authorized to perform: sts:AssumeRole on arn:aws:iam::xxxxxxxxx:role/xxxxxxxxx (Service: AWSCodeBuild; Status Code: 400; Error Code: InvalidInputException; Request ID: xxxxxxxxxxxxxxxx; Proxy: null)

您知道为什么会出现这种情况或者我该如何解决这个问题吗？

谢谢

使用 Arn 而不是 RoleId 导出角色解决了问题，谢谢@Marcin

输出失败:

  CodeBuildRemoveRoleId:
    Description: ID of role used by remove codebuild project
    Value: !GetAtt CodeBuildRole.RoleId
    Export:
      Name: cb-remove-role-id

传递输出:

  CodeBuildRemoveRoleId:
    Description: ID of role used by remove codebuild project
    Value: !GetAtt CodeBuildRole.Arn
    Export:
      Name: cb-remove-role-id
