Investigation
debugpy.pydevd.log contains logs like the following.
0.00s - Request for breakpoint in: \\10.123.36.238\shamada\debug\b.py line: 3
0.00s - pydev debugger: replacing to server: \\10.123.36.238\shamada\debug\b.py
0.00s - pydev debugger: sent to server: /home/shamada/debug\b.py - matched prefix: \\10.123.36.238\shamada\
0.00s - Breakpoint (after path translation) in: /home/shamada/debug\b.py line: 3
0.00s - os.path.exists('/home/shamada/debug\\b.py') returned False.
It seems that the cause is that slashes and backslashes are not converted properly in path mapping.
Please see the attached file for all logs.
