Debugging Arduino Zero

[SebastianZug]

Hi guys,

I would like to debug code for an Arduino Zero. I added a general configuration file (Arduino path, etc.) and following project .vscode file

"board": "arduino:samd:arduino_zero_edbg",
"debugger": "CMSIS-DAP", 
"port": "/dev/ttyACM0", 
"sketch": "Analog.ino".

Compiling and flashing works fine, the controller is connected via USB "Debug" port. But I receive always a

"Cannot read property ''apply" of undefined - Source: Arduino(Extension)"

message when I try to debug. Do I have to add additional variables to the configuration? Anyone knows a detailed description of configuration parameters for this type of controller?

Thanks in advance

Sebastian
