Issue with west ncs-provision upload during DFU provisioning on nRF54L15DK

[darav]

I'm following the Lesson 9, Exercise 2: DFU over USB - Adding External Flash from the Nordic Academy: Tutorial Link

SoC: nrf54l15

SDK version: 3.0.2

Toolchain version: 3.0.2

Problem:

I am able to follow the tutorial properly up untill the KMU provisioning step. 

But for the provisioniing command:

west ncs-provision upload -s nrf54l15 -k private_key.pem

I am getting: 

nrfutil device x-provision-keys --key-file C:\Users\Admin\AppData\Local\Temp\nrfutil_jf766dmw\keyfile.json --traits jlink
Traceback (most recent call last):

ModuleNotFoundError: No module named 'constants'

Uploading failed!

What I’ve Tried:

• I downgraded protobuf to 3.20.x as previously suggested in other threads.

• Verified that nrfutil and west are both from the NCS v3.x toolchain.

• Verified my key file is valid and present.

• I'm running this on Python 3.12

Hi, where are you running the command from? If you are using VSCode, go to NRF Connect, open the terminal and run the command there.
if this doesn't work, run "Get-Command nrfutil | Select-Object Path" (in the VSCode terminal) or "where nrfutil" in CMD

or 

"which nrfutil
type -a nrfutil" if Mac or Linux

The path should be something similar to this "C:\ncs\toolchains\b8b84efebd\nrfutil\bin\nrfutil.exe". If it's not, set it to the correct nrfutil.exe

i added the nrfutil exe file to the location as mentioned - "C:\ncs\toolchains\b8b84efebd\nrfutil\bin\nrfutil.exe" and verified using "Get-Command nrfutil | Select-Object Path" which outputs the same path.
now the "west ncs-provision upload -s nrf54l15 -k private_key.pem" commands works with output as - 

west ncs-provision upload -s nrf54l15 -k private_key.pem
nrfutil device x-provision-keys --key-file C:\Users\Admin\AppData\Local\Temp\nrfutil_lq2m1dbw\keyfile.json --traits jlink
Uploaded!

And on flashing the code, the device is getting stuck into bootlooder itself in the "FIH_PANIC;" of the main.c in bootloader.
