GPIO simulator

[homevk15]

Hi. If I type
#import modules
import RPi.GPIO as GPIO
in the code form of the website https://tools.withcode.uk/create/ I get the error
ExternalError: TypeError: a is undefined on line 2 (in Firefox)
ExternalError: TypeError: Cannot read properties of undefined (reading 'v') on line 2 (in Google Chrome)
Could you tell me how to run a GPIO simulator properly?

Does'nt exactly solve the problem, but try another website; https://create.withcode.uk/ It works fine in this one
