This is 🐛 Bug Report

[MrArnoldPalmer]

Hey @OlegBoulanov, what version of NodeJS are you currently running?

There is a known issue with JSII that you may be running into. Check out aws/jsii#992 for context on that.

[OlegBoulanov]

C:\Users\source\repos\cdk-test-app>node --version

v12.7.0

And yes, due to corporate IT policies and regulations, we must have McAfee on all computers

[MrArnoldPalmer]

Gotcha. I'm gonna close this as a duplicate of aws/jsii#992. We will track the fix there. In the meantime you can try the retry workaround mentioned in that issue, though its not ideal.
