Is there an existing issue for this?

I have searched the existing issues

Summary

Hello! Just moved from postman to hoppscotch and found a strange behaviour: unknown error when I try to take a variable from json response and save it to env variable. Example:

Response:
{ "id": 4065 }

And the reason is 'id' in response is a number. After I wrapped it with "String(res.id)" this error was resolved.

After that i have 2 suggestions:

Looks like it will be great to wrap the 2nd arg of pw.env.set method with "String" and accept any kind of variables (boolean/number/...). Because I found the solution only after I manually put a number as the 2nd arg. Or if it's expected behaviour can I contribute and add this solution to the official docs?

It will be very helpful to show any error logs for scripts. Even raw logs with stacktrace. It will help with future pre/post-request scripts debug sessions :)

Why should this be worked on?

This case is one of the most popular I guess
This feature will help in future pre/post-request scripts debug sessions
