I’m running into a problem where I don’t even know where to start looking for the problem. Well, it seems that there is an undefined variable in the error\_handler.jl file so I’m guessing it might be a bug in the VSCodeDebugger extension?

My debugger crashed on me with the following error message:

┌ Error: Some Julia code in the VS Code extension crashed

I just published a new prerelease version (1.129), can you try again with that? I think this should be fixed there.

It seems to be working now. Thanks!

One other question: there is an issue with the breakpoints. I can not remove them while the code is running. I tried, but even though the breakpoint is no longer listed and there is no red dot indicating the presence of a breakpoint, the code still stops on the same spot.

Ah, could you open an issue? Over at DebugAdapter.jl ideally.

Hi David, I have a similar issue with debugging but 1.129 does not fix the problem. Should I make a new post?

Thanks for the reply. Do you mean issues on GitHub? If so, I created one 2 years ago about this issue but it was never answered. I was hoping to get help here for this reason.
