Breakpoints no longer being sent #1293
Description
Breakpoints appear to no longer be sent by DAP, neither during initial attach, nor if I add/remove a breakpoint while the debug session is active.
Looking at the message trace, I see setExceptionBreakpoints being sent with an uncaught exception breakpoint, but setBreakpoints is never sent.
PyCharm definitely thinks I have a breakpoint set:
But my attach trace looks like this:
Attaching 'Python- Debugpy' at main:5678

I'm using 0.16.1 plugin, but I also tried with every version down to and including 0.11.0 with no luck. Maybe there was a platform change in the Intellij platform that broke something?
I'm using PyCharm 2025.2.0.1
