graalpy can not set breakpoints

[EricCD-S]

Hi, I've recently been trying to build a debugging client using graalpy as an adapter, and most of the functionality works fine, but the request "setBreakpoints" doesn't work. At the end of the running will get "[Graal DAP] Error: null". May I ask how you guys solved this problem while writing the code? Thanks

Hi @EricCD-S I don't remember seeing this particular issue, but it also was early this year. You don't see this problem in our example or do you?

#842
I find this merge history and the problem I meet seems very similar to this one. Graalpy can not hit breakpoint and get "[Graal DAP] Error: null" when program finish. So I am thinking the same problem may have already been solved?

I tried change file path format. But it doesn't work.

Hi @EricCD-S a I forgot about this one:
It is this commit 36687a7 The paths weren't the same. Even if created unix style on the client side the paths come back with backslashes on Windows. 🤷‍♂ Therefore I introduced this "hack" in the referenced commit.

I tried different path format, but this question still exists. May be i miss some parameters or the order of my requests has something wrong. I am trying debugpy to see if it meets my needs.

Try printing the paths on both sides. I overlooked the subtle differences when I came across the problem. Are you on Linux, Windows or Mac?

it turns out the path format makes this problem. i tried different format, finally one works! thanks for pointing that out.
