(aws-cdk-lib/pipelines): (muliple s3 sources from same bucket fails)

[mariusingjer]

Describe the bug

I add two files from the same s3 bucket as source:

    new pipelines.CodePipeline(this, 'pipeline', {
      synth: new pipelines.ShellStep('Build-codepipeline-and-self-update', {
        input: pipelines.CodePipelineSource.s3(
          artifactsBucket,
          'some-artifact.zip', {
          trigger: cdk.aws_codepipeline_actions.S3Trigger.NONE,
          actionName: 'source-nr-1'
        }),
        additionalInputs: {
          'somewhere': pipelines.CodePipelineSource.s3(
            artifactsBucket,
            'another-key-same-bucket.zip', {
            trigger: cdk.aws_codepipeline_actions.S3Trigger.NONE,
            actionName: 'source-nr-2'
          }),
        },
        commands: [
          '...',
        ],
      }),
    });

Fails with:

A workaround is to import the same source bucket twice in the stack.

    new pipelines.CodePipeline(this, 'pipeline', {
      synth: new pipelines.ShellStep('Build-codepipeline-and-self-update', {
        input: pipelines.CodePipelineSource.s3(
          bucket: // import bucket first time here,
          'some-artifact.zip', {
          trigger: cdk.aws_codepipeline_actions.S3Trigger.NONE,
          actionName: 'source-nr-1'
        }),
        additionalInputs: {
          'somewhere': pipelines.CodePipelineSource.s3(
            bucket: // import bucket second time here,
            'another-key-same-bucket.zip', {
            trigger: cdk.aws_codepipeline_actions.S3Trigger.NONE,
            actionName: 'source-nr-2'
          }),
        },
        commands: [
          '...',
        ],
      }),
    });
