[BUG] Error on activation script: bash: scripts/setup/gen_pigweed_cipd_json.py: No such file or directory

[locnnil]

Reproduction steps

The problem

I've following the documentation present here and using instructions present here to check out the components for a specific platform. But when I try to run the activation script, I got:

bash: scripts/setup/gen_pigweed_cipd_json.py: No such file or directory

It happens:

Whenever I try to follow the documentation to try to compile the lightning app example.

Steps to reproduce

• Install the dependencies

sudo apt-get install git gcc g++ python3 pkg-config libssl-dev libdbus-1-dev libglib2.0-dev ninja-build python3-venv python3-dev unzip

• Install ZAP

wget --no-verbose https://github.com/project-chip/zap/releases/download/v2024.04.03/zap-linux-x64.zip

mkdir zap

unzip  zap-linux-x64.zip -d zap

cd zap 

ZAP_INSTALL_PATH=$PWD

cd ..

• Clone the repository:

git clone --depth=1 git@github.com:project-chip/connectedhomeip.git

• Get submodules for Linux platform:

cd connectedhomeip && ./scripts/checkout_submodules.py --shallow --platform  linux

cd ~/connectedhomeip/examples/lighting-app/linux

• Go to the lighlighting-app Linux folder and run the activation script:

cd examples/lighting-app/linux/

source third_party/connectedhomeip/scripts/activate.sh

Then the output is:

docker@72911bd09d95:~/connectedhomeip/examples/lighting-app/linux$ source third_party/connectedhomeip/scripts/activate.sh 
bash: scripts/setup/gen_pigweed_cipd_json.py: No such file or directory

I'm doing these steps from a container based on Ubuntu 22.04 image.
Not sure if it's a bug or an error on documentation.
