Reproduction Steps

Code is provided in the ticket. Repro'd issue with adding the policy manually -

     testbucket = s3.Bucket.from_bucket_attributes(self, "MyTestBucket", bucket_name="mytestbucket1503",
                   bucket_arn="arn:aws:s3:::mytestbucket1503",)

    iamrole = iam.Role(self, "MyRoleBucket",assumed_by=iam.ServicePrincipal('cloudtrail.amazonaws.com'))

    iamrole.add_to_policy(iam.PolicyStatement(
        effect=iam.Effect.ALLOW,
        resources=[testbucket.bucket_arn],
        actions=["s3:GetBucketAcl"],
        conditions={"StringEquals": {"s3:x-amz-acl": "bucket-owner-full-control"}},
    )) 

    iamrole.add_to_policy(iam.PolicyStatement(
        effect=iam.Effect.ALLOW,
        resources=['*'],
        actions=["s3:PutObject"],
    )) 

    trail= cloudtrail.Trail(self, "CloudTrail",
                            send_to_cloud_watch_logs=True,
                            bucket=testbucket,
    )

same here, with isOrganizationTrail: true

• you can see how much workaround done here https://github.com/awslabs/landing-zone-accelerator-on-aws

"GetBucketAcl" policy should have condition assessing for trail arn instead of s3:x-amz-acl I believe 🤔 An example from the project I work on:

    this.bucket.addToResourcePolicy(
      new iam.PolicyStatement({
        sid: "AWSCloudTrailAclCheck20150319",
        effect: iam.Effect.ALLOW,
        principals: [new iam.ServicePrincipal("cloudtrail.amazonaws.com")],
        actions: ["s3:GetBucketAcl"],
        resources: <bucket arn>,
        conditions: {
          StringEquals: {
            "AWS:SourceArn": <array of trail ARNs>,
          },
        },
      })
    );
