Maximum call stack size exceeded - python 3.6 - jsii 0.21.1

[medbensalem]

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

[MrArnoldPalmer]

Hey there! Some questions for you about this issue.

1. Was the code that is currently breaking working with previous versions of CDK or JSII?
2. Was the application working as expected until it got beyond some certain # of stacks or beyond some other parameter that you know of?
3. Can you provide some high level information about the layout of your stacks? I.E. Stack one creates VPC and security groups, Stack 2 creates ECS Cluster referencing VPC and SGs from Stack 1 etc...
4. Also when you say deploying stacks simultaneously, does that mean deploying a single stack that has dependencies on other stacks that then get auto-deplyoed or does that mean cdk deploy Stack1 Stack2 Stack3 and the stacks don't necessarily depend on each other?
5. Does the code break on any command other than deploy? i.e.cdk diff or cdk synth

Looks like this could be stemming from a known issue with JSII running on NodeJS >= 13.2. What is your current Node Version?

See aws/jsii#1142 for more info on that.

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

[medbensalem]

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

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

worked for me too!
