(aws-imagebuilder): "The value supplied for parameter 'distributions[0]' is not valid" deploying a distribution configuration

I have an EC2 Image Builder image pipeline stack that works fine when I deploy it without a distribution configuration. When I add a distribution configuration the stack deployment fails during the distribution step.

Reproduction Steps

The following simplified stack, extracted from my complete pipeline stack, is reproducing the same issue:

#!/usr/bin/env python3

from aws_cdk import core, aws_imagebuilder as imagebuilder


class DistrConfigStack(core.Stack):

    def __init__(self, scope: core.Construct, construct_id: str, **kwargs) -> None:
        super().__init__(scope, construct_id, **kwargs)

        # Image distribution configuration 
        distrconfig = imagebuilder.CfnDistributionConfiguration(
            self,
            'DistrConfig',
            name='DistrConfigTest',
            distributions=[
                imagebuilder.CfnDistributionConfiguration.DistributionProperty(region='eu-west-1'),
                imagebuilder.CfnDistributionConfiguration.DistributionProperty(region='eu-central-1')
            ]
        )

        # Outputs
        core.CfnOutput(self, 'DistrConfigCfnOutput0', value=distrconfig.distributions[0].region)
        core.CfnOutput(self, 'DistrConfigCfnOutput1', value=distrconfig.distributions[1].region)


app = core.App()
config_ami = DistrConfigStack(app, "Distrconfig", env=core.Environment(region='eu-west-1'))
app.synth()

What did you expect to happen?

My goal is to deploy an Image Builder pipeline stack that includes distribution of the EC2 image to a number of AWS regions.

What actually happened?

When I add the distribution configuration in my pipeline stack, however, the deployment fails.

When the stack deployment fails the following error is shown:

The value supplied for parameter 'distributions[0]' is not valid. One or more outputs should be provided for each region in a distribution configuration. (Service: Imagebuilder, Status Code: 400, Request ID: 7d5036b5-e982-476b-9694-5eab88737efe, Extended Request ID: null)

Environment

• CDK CLI Version : 1.88.0 (and same version also for all the Python CDK packages)
• Framework Version:
• Node.js Version: v10.19.0
• OS : Ubuntu 20.04
• Language (Version): Python (3.8.5)

Other

In case it helps, this is the output of cdk synth:

Resources:
  DistrConfig:
    Type: AWS::ImageBuilder::DistributionConfiguration
    Properties:
      Distributions:
        - Region: eu-west-1
        - Region: eu-central-1

Outputs:

    Value: eu-central-1

For CDK Image Builder I could not find any examples of image pipeline stacks including distributions: it would definitely help seeing one.

it’s not marked correctly as such in the model…?

I think that could be the case, anyway at the moment the issue for me is solved and I do not need additional support. Again, thanks for your help.
