Cannot run ZAP tool

[Dan]

Hi - I am trying to modify the Matter template sample with my own clusters as documented in: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.3.0/nrf/protocols/matter/getting_started/adding_clusters.html#ug-matter-creating-accessory 

I was previously able to do so when using v.2.1.0 of the SDK. 

Now, with a clean install of v.2.3.0 of the SDK I am getting the following errors when trying to install ZAP. I am on Mac OS 13.1 (22C65). I welcome any guidance or suggestions.

Thanks! Dan.

Hi, 

Please try to replace https://github.com/nrfconnect/sdk-connectedhomeip/blob/v2.3.0/scripts/setup/nrfconnect/get_zap.py#L121 with 

zap_executable = 'zap.app/Contents/MacOS/zap'

Guess that should fix the problem.

Regards,
Amanda H.

Hi Amanda - thanks for getting back to me so quickly on this - much appreciated.

Your suggestion did work and allowed the script to complete properly. However, I am still unable to run the zap script. I am on an Apple M1 Max.

[this does not launch the electron browser; 
if I use chrome to go to:http://localhost:9070
I do get the ZAP tool interface, but cannot load or see the template.zap file]

Separately, it seems like either the scripts or the documentation should be corrected to deal with some of the issues that came up  (e.g. despite going through the automated toolchain setup, python path was not correct, wget wasn't installed etc).

Welcome your further guidance on how I can edit the template.zap file on an M1 Mac with the v.2.3.0 of the SDK.

Thanks! Dan.

Hi Dan,

I've exactly the same problem. The same procedure, the same result. Also tried to download release from chip github, but I don't see matter products when adding endpoint 0. 

[Vidar Berg]

I had another private ticket related to the same issue, and I discovered that I had to extract the zip manually instead of using the Python script for some reason:

"I was finally able to reproduce the same error here, and it appears to be related to how the zip file is being extracted by the Python script.

Please change the directory to /opt/nordic/ncs/v2.3.0/modules/lib/matter/location_path in the terminal and delete the existing files and folders before running this command.

"wget github.com/.../zap-mac.zip && unzip -d zap-mac zap-mac.zip && ../../../../nrf/samples/matter/sensor/src/template."

After the zip is downloaded and extracted, make sure that both /opt/nordic/ncs/v2.3.0/modules/lib/matter/location_path/zap-mac/zap.app/Contents/MacOS/ and /opt/nordic/ncs/v2.3.0/modules/lib/matter/location_path/zap-mac/ are added to PATH.

I have reported this as a bug internally. It seems like only macOS is affected by this.

Hi Vidar,

thanks for your answer. I followed your instructions and it looks zap tool works!
Unfortunately when opening zap tool with
```
zap src/template.zap
```
in my project folder I cannot add any matter endpoint. Is there any extension which I should add to see Matter clusters? 

[Vidar Berg]

Good to hear that it worked. Are you opening the terminal via the toolchain manager? This will ensure that the necessary env. variables are exported/set.  

[filipmrazek]

Okay, my project was outside `/opt/nordic/ncs/v2.3.0`.
I generated environment script with toolchain manager, executed the script and finally I see available matter clusters!
Thank you for your time. 

[Dan]

Bless you Vidar Berg  - this worked! To the Nordic team: hopefully the scripts or the documentation can be updated - it would save a lot of time/frustration. Thanks! Dan.
