Not able to debug tests.

[kujtimiihoxha]

I am using nvim-dap-go and neotest-golang ontop of astronvim. I think I am adding all the necessary configuration but for some reason it is not working I tried reading the dap logs but can't figure out what the issue is

Is delve on your $PATH?

[kujtimiihoxha]

Yep, was wondering the same:

[fredrikaverpil]

I'm sorry but I'm not sure how to help you out here, as it's a configuration problem on your end, it seems.

[kujtimiihoxha]

Yep you are probably right, was wondering if this is something you came across before, I will have to dig more :( . I will close this for now and report back with a fix if I find it.

[fredrikaverpil]

If you open ~/.local/share/nvim/lazy/nvim-dap/lua/dap/session.lua and go to line 950 or around there (which is where your log indicates the error is hit), you can try do some poor man's printing with print(vim.inspect(some_variable)).

When I go in that file onto line 950, it looks like we are likely on different versions of nvim-dap. But I see a Session:handle_body method, which is interesting, and in which you could e.g. print the body to perhaps gain some insight about what is going wrong.

[fredrikaverpil]

You can also try commenting out all the other DAP plugins you're using, to verify they are not conflicting with neotest-golang and/or nvim-dap-go.

Thanks a lot @fredrikaverpil this helps a ton, very new to neovim and lua so this is super helpful, I will report back 👍
