Breakpoints not hit when using libraries in sub-folders

[varunpatro]

Here's my folder structure:

bin/main.m 
lib/a.ml
lib/b.ml

I'm using dune to build an executable in the bin/ folder and a library in the lib/ folder.

When I use vscode to debug, I'm able to set breakpoints in the bin/main.ml and when the program starts, it pauses at those breakpoints. However, if I set breakpoints in the lib/a.ml file, the program doesn't pause when it reaches the line in lib/a.ml.

However, when I set a breakpoint in bin/main.ml and debug, if I use the debug controls such as step-over, i am able to reach the lines in lib/a.ml but setting breakpoints in lib/a.ml still doesn't work.

Try add dotMerlins config option to launch configuration. Don't forget add the one in subfolder. There's example in README.md

It's telling me for dotMerlins "Property dotMerlins" is not allowed"

Info on version I installed from vscode below. Is there a more up to date version I should be using?
