Python version throw an error

[thomaspoignant]

Hi,

I am trying to use the python version of the library and when I run cdk synth I got the stack bellow. I don't know that much how JSII works but the problem seems related to source-map-support/register.

jsii.errors.JavaScriptError:
  internal/modules/cjs/loader.js:1033
    throw err;
    ^

  Error: Cannot find module 'source-map-support/register'

The above exception was the direct cause of the following exception:

Hey @thomaspoignant - I'm sorry to hear you're having problems with the library. I primarily use cdk on Node, so I haven't experienced this. I just generated a Python test project and ran into the same error you're experiencing.

I'll need to find some time to debug this problem. In the meantime, if you need this behavior, you could take a look at the source code and translate it over to Python or use the Node version of the library that should work.

Thanks for the report and sorry it didn't work out of the box.

That's what I did, but I wanted to open this issue to let you know 👍

[blimmer]

Awesome! I'm glad to hear that you're unblocked and I appreciate you letting me know 😄

[blimmer]

This should be fixed in v1.3.2 and beyond. Thank you for your report!

[thomaspoignant]

Awesome thank you 👍
