How to reproduce the issue

set NVIM_DATA_MINIMAL=<temp dir>
set NVIM_APP_NAME="nvim-minimal"
nvim -u minimal.lua
<open rust project>
:RustLsp debuggables
<select main>

Expected behaviour

Should start DAP successfully

Actual behaviour

Should also note that if I use a custom fork of rustaceanvim and comment out the call to get_lldb_commands, then debugging works fine

[svermeulen]

The python file it is referencing does not exist at that location. I also tried the stable release of rust and it didn't have that file either.

Hey :wave:

Thanks for reporting. I'll see if I can come up with a fix soon. In the meantime, you can work around it by disabling it:

vim.g.rustaceanvim = {
  dap = {
    load_rust_types = false,
  },
}
