Error only while using debugger in VSCode

Hello - I’m unable to use the debugger in VSCode while using the KernelAbstractions.jl library. I have shared details along with a minimal reproducer here:

Possible error due to KernelAbstractions while using VSCode debugger

hello - I'm able to run a script based on an Oceananigans example in VSCode, but… get an error while using the VSCode debugger on the same script that runs fine. I've shared details incl screenshots and code here: https://github.com/CliMA/Oceananigans.jl/issues/3171 It looks like the error has something to do with the usage of KernelAbstractions - one of the authors of the Oceananigans library has added a comment in the issue above specifically, this line of code leads to the error: https://github.com/JuliaGPU/KernelAbstractions.jl/blob/main/src/cpu.jl#L44 it'd be very helpful if someone who has run any KernelAbstractions code with VSCode could please share some feedback to help us resolve the issue. I've also opened an issue on the julia-vscode extension github repo here: https://github.com/julia-vscode/julia-vscode/issues/3349 thank you

Error only while debugging in VSCode

Hello - I'm able to run a Julia script in VSCode, but when I set breakpoints and… run in Debug mode, the same code throws an exception. I have described the issue in detail with screenshots and the exact error here: https://github.com/CliMA/Oceananigans.jl/issues/3171 the issue is due to some functions returning the value of variables (boundary condition values more specifically) as `nothing` , which is not an error, and as I mentioned before, when I run the script, it runs fine. I hope the thread in the linked issue provides more information. I'd greatly appreciate any help figuring out how to resolve this issue so I can use the debugger. Thank you!

essentially - I’m able to run the script fine in VS Code, but I only get the errors shown in the screenshots in the issues when I set breakpoints and step through the code

I’d greatly appreciate any help - thank you!

You could try using Debugger.jl instead, I believe it’s separate from the VsCode debugger so it might work.

thank you for replying - I looked at Debugger.jl and will def try that - I’m used to the VSCode debugger and would like to inspect the code and values of variables as I step through the code of a library without modifying it - I’ll look into some more

I’d be super grateful if someone could try out the reproducer - I think quite a few folks would find the VSCode debugger helpful

thank you again!
