RTT debugging not working on nrfConnect for vs Code 2025.4.106

Question

The latest toolchain has removed "serverArgs": from debug configuration in nrfConnect 2025.4.106

Is is mandatory as we only have RTT on our FF board and no serial port. 
 We are normally adding following line, to add RTT debugging on nRF54L15: 
 
 "serverArgs" : "-if swd -device nRF54L15_M33 -select usb=${snr} -speed 4000 -port ${port} -singlerun -nogui -halt -noir -silent -rtos ${rtosPlugin}"

Please FIX ASAP

Hi, 
 'serverArgs' was changed to 'gdbServer'. Could you try this: 
 "gdbServer": {
 "address": "127.0.0.1:${port}",
 "args": {
 "if": "SWD",
 "speed": 4000,
 "device": "nRF54L15_M33",
 "select": "usb=${snr}",
 "port": "${port}",
 "rtos": "${rtosPlugin}",
 "jlinkscriptfile": "${jlinkScript}",
 "additionalArgs": [
 "singlerun",
 "nogui",
 "halt",
 "noir",
 "silent"
 ]
 }
 }
