(cloudfront): jsii.errors.JSIIError: Cannot read property 'uniqueId' of undefined

getting this error when ‘cdk synth’ is run. I have pasted the entire code. It is the example code specified on reference docs.

Reproduction Steps

from aws_cdk import ( 
    core,
    aws_cloudfront as cfront,
    aws_cloudfront_origins as cforigins,
    aws_s3 as s3,
    aws_certificatemanager as acm
)
from variables_list import (
    Project,
    Env
)

class CdnStack(core.Stack):

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

        # The code that defines your stack goes here
        core.Tag.add(self,key='environment',value=Env)
        core.Tag.add(self,key='project',value=Project)

        my_bucket = s3.Bucket(self, "myBucket")

        cfront.Distribution(self, "myDist",
        default_behavior= cfront.BehaviorOptions(
            origin=cforigins.S3Origin(my_bucket)
            )
        )

What did you expect to happen?

I am trying to create CloudFront distribution with s3 origin.

This is 🐛 Bug Report

Ah, that’s the issue then; the Distribution construct was released in version 1.52.0. When you use the CDK, all versions must be in sync – you can’t use 1.52.0 (or newer) of CloudFront and 1.34.0 of Core.

Your options are either to go through the work of upgrading your application to a newer version, or using the CloudFrontWebDistribution construct instead of Distribution.

I’m going to resolve this, but feel free to reopen if you have any follow-up questions.
