Unable to debug a Nucleo-L053R8

Dear,
I tried to install OpenSTM32 on MacOS, and it worked flawlessly.
Nevertheless when I tried the getting started
: I am able to compile and flash the µC, but I can’t enter in debug mode.
I use the Nucleo-L053T8 board, it can be debugged under Keil software so I don’t think that it is related to the hardware.
Following are my code and the console output. I tried to look over the Internet but did not find similar issues, and I am not familiar with STM32 toolchains :/
Do you have any idea ?
Thanks
