Modules in byte code executable file build by dune are not found when adding fragment in Controller.root function.

I have noticed that we can not set breakpoints in vscode for dune build bc executable file, and i build a custom earlybird with printting some logs in the console, the logs show that some modules are not found when adding fragment.
Below are some parts of the console log.

Have you noticed https://github.com/hackwaly/ocamlearlybird?tab=readme-ov-file#breakpoints-not-hit-with-lang-dune-30-and-above
Thanks for the reply, i have already changed my dune version to 3.7 and set (map_workspace_root false), the breakpoints are still unrerified.
You could set source_dirs in launch.json to specify additional search dirs. See
Sadly, looks like it hasn't implemented.
Yes, this still not fix my problem.
And i noticed that the module name has been changed in the debuginfo of bc executable file. Eg, the source file is Cli.ml, but it changed to Dune__exe__Cli, did this changes will break the module resolving? I am not very familar with ocamlearlybird code.
I think it won't. You can log the search_dirs and dig into search_dirs to see what's inside. Maybe this will give us some clues.
I logged the search dirs, the log shows it searches in path /workspace_root, i don't know what the path /workspace_root mean, it does not existed in my wsl2 ubuntu system.

It seems your (map_workspace_root false) not takes effect.
Ohh! sorry, it's my fault, i forgot to change map_workspace_root true to false!! It works now, thank you!
