How to access the code in vs code

[pankajsoni91]

@rakshithcgowda I'm sorry I didn't get what you wanted to ask.

[rakshithcgowda]

@pankajsoni91 Like I am asking that see there is an bug in the code we want to debug it right where can we access that code. Or do we need to start from scratch and build entire thing###

[pankajsoni91]

I don't have a sample code. but facing this issue very often.

I can say we're still on React 17, and are unable to upgrade yet (some work needed on our codebase to remove a deprecated library)
