[aws-cdk-pipelines] Cannot assume role by code pipeline on code pipeline action AWS CDK

[chamakov]

Describe the bug

Hello there,

Im receiving an error when I try to deploy a CDK template using python. The message says "XXX is not authorized to perform AssumeRole on role XXXXX (Service: AWSCodePipeline Error Code: InvalidStructureException) (module name): (short issue description)"

Im not using a constructor for the core CodePipeline but im using the examples from the documentation:

`
from aws_cdk.pipelines import CodePipeline, ShellStep, CodePipelineSource, ManualApprovalStep

Creating a pipeline with a manual approval step.

    pipeline =  CodePipeline(self, "Pipeline-IVR-" + stage, 
                    pipeline_name="Pipeline-IVR-" + stage,
                    synth=ShellStep("Synth", 
                        input=CodePipelineSource.s3(s3Bucket, "infraIVR.zip"),
                        commands=["npm install -g aws-cdk", 
                            "python -m pip install -r requirements.txt", 
                            "cdk synth"]
                    )
                )`

If I try to deploy the same package on another account all is OK

Expected Behavior

I expect to be able to deploy the base pipeline

Current Behavior

Im receiving an error when I try to deploy a CDK template using python. The message says "XXX is not authorized to perform AssumeRole on role XXXXX (Service: AWSCodePipeline Error Code: InvalidStructureException) (module name): (short issue description)"

Reproduction Steps

This isn't really a bug report but a request for assistance in debugging an account's permissions setup. That's not what GitHub issues are for, I'm converting this to a discussion and hope someone else will be able to assist you there.
