Maximum call stack size exceeded - python 3.6 - jsii 0.21.1

We are currently working with CDK to deploy multiple stacks that create an ECS Cluster/tasks and ALBs. Deploying more than a certain number of stacks simultaneously creates the error reported bellow. Deploying the stacks individually works perfectly. I wanted to note that in my code I’m passing some cdk objects from stack to stack like in the example in this link: https://github.com/aws-samples/aws-cdk-examples/blob/master/python/codepipeline-docker-build/Base.py#L68-L70 https://github.com/aws-samples/aws-cdk-examples/blob/master/python/codepipeline-docker-build/app.py#L12-L15

Reproduction Steps

I don’t have any easy way to reproduce the steps without sharing confidential code.

This is 🐛 Bug Report

[medbensalem]

I confirm that reversing back to node 12, solved the issue.

@MrArnoldPalmer I was experiencing this issue. Using nvm use 12 to force my node version from 13.7 to 12 did the trick. Thanks!
