Is this a bug in CDK v2 codebuild.Project() construct? The Docker image parameter gets corrupted.

Question

I have this CDKv2 code (fragment shown below):

```
        const dockerImageUriParameter = ssm.StringParameter
            .fromStringParameterName(
                this, 'DockerImageUriParam', '/codebuild-image-uri');

const ecrRepo = ecr.Repository.fromRepositoryName(
            this, 'EcrRepo', dockerImageUriParameter.stringValue);

const dockerImage = codebuild.LinuxBuildImage.fromEcrRepository(ecrRepo);

const project = new codebuild.Project(this, 'AppCodeBuildProject', {
            projectName: cdk.Stack.of(this).stackName,
            description: 'my Application CodeBuild Project',
            environment: {
                privileged: true,
                computeType: codebuild.ComputeType.MEDIUM,
                buildImage: dockerImage
            },
            ... rest of code omitted for clarity ...
```

Upon inspection in the AWS Console, I see that the SSM parameter has the correct value, something like:

```
123456789012.dkr.ecr.us-west-2.amazonaws.com/cdk-xxxxxxxxx-container-assets-123456789012-us-west-2:888888e16a7935f3e9488835692573393ae1372efa06fd469999999999999999
```

However, the codebuild project gets configured with an incorrect-looking (based on Console inspection) image uri:

```
123456789012.dkr.ecr.us-west-2.amazonaws.com/123456789012.dkr.ecr.us-west-2.amazonaws.com/cdk-xxxxxxxxx-container-assets-123456789012-us-west-2:888b01e16a7935f3e9488835692573393ae1372efa06fd469999999999999999
```

Note how part of the URI is repeated.

What is going on here?

Accepted Answer

Still unclear whether that was a bug, but this works instead:

```
        const dockerImageUri = cdk.Fn.importValue('BuilderImageUriExport');
        const dockerImage = codebuild.LinuxBuildImage.fromDockerRegistry(dockerImageUri);
```
