Can I debug this board with pyOCD?

I have just seen that pyOCD supports stlinkv2 and installed version 0.14.3 using pip. I know that the board isn't supported directly, but wanted to try using GDB to debug code. However, when I try to start pyOCD using the generic cortex_m target I get an exception. Is this expected to be possible (and I'm missing something) or is this a non-starter?

The exception is as below:

0000830:INFO:board:Target type is cortex_m
0000846:INFO:dap:DP IDR = 0x2ba01477
0000857:ERROR:__main__:uncaught exception: 0
