TypeError: Class constructor BaseAPI cannot be invoked without 'new'

[andreafalco1991]

Typescript: 3.6.3

After i have generate the api.ts with openApi Generator 4.2.2 i found the error "TypeError: Class constructor BaseAPI cannot be invoked without 'new'".
After some hours of debug i found the probable problem.
There is a function called like "xxxPublicxxx".
If i remove "Public" from the function name it seems to work correctly.

One more info:
the function belong to a class defined like "export class Aaa extends BaseAPI {"
and doesn't have the constructor because the constructor is inside BaseAPI.

To expedite the triage process, we need everyone to follow the issue template and instructions.

When you clicked "Create New Issue", the issue form was pre-populated with a template and some instructions. We need you to read those instructions completely, follow them, and then fill in all the fields in that template.

We are not able to assist with issues that don't follow the template instructions as they represent a significantly larger amount of work compared to issues which are correctly specified. Thank you for understanding.

I hit this as well. I had "target": "esnext" in my tsconfig.json. If I removed that then it worked
