Debugger crash after stepping through `@generated`

[baggepinnen]

Stepping through this call crashes the debugger ~and it remains crashed after julia is restarted, one has to restart vscode to recover.~ Scratch that, I just tested again and this time it worked to just restart the julia process

@generated function foo(x)
    x
end

bar(x) = foo(x)

julia> @enter bar(1)

Error while running the debugger (consider adding a breakpoint for uncaught exceptions):
ERROR: Method is @generated; try `code_lowered` instead.

I am also running into this same error message when using the vscode debugger. When I set a breakpoint in a function, and that function contains a call to Zygote.gradient(), then the debugger will fail. Just wanted to suggest that this problem is happening in other contexts too. Thanks.

Just wanted to upvote and mention that I also run into this error after disabling Uncaught Exceptions.
