Issue Launching ZAP GUI with Custom Cluster in NCS v3.0.0-preview2

[Rahul_Chauhan]

Hello Team,

I’m working on creating a custom Matter cluster using the instructions provided in the Nordic documentation: https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/protocols/matter/getting_started/custom_clusters.html#ug-matter-creating-custom-cluster

I’m currently using NCS v3.0.0-preview2 and have successfully completed Step 1 using the following command:

1.west zap-append /home/rahul/Downloads/MyCluster.xml \
-b /home/rahul/ncs/v3.0.0-preview2/modules/lib/matter/src/app/zap-templates/zcl/zcl.json \
-o ~/nrf/template/zcl.json

This correctly created the zcl.json file at ~/nrf/template/zcl.json, which includes both standard and my custom cluster.

However, when I proceed to Step 2 and try launching the ZAP GUI with the following command:

cd ~/nrf/template
2.west zap-gui -j ./zcl.json --clusters /home/rahul/Downloads/MyCluster.xml

I encounter an error.

I also tried running just:

west zap-gui -j ./zcl.json

But that also results in an error. Unfortunately, the documentation doesn’t specify what the exact requirements are for this version of NCS, or how to troubleshoot west zap-gui issues.

Could you please help me understand how to resolve this? Is there a known issue with west zap-gui in v3.0.0-preview2, or is there an alternative method I should try?

Please let me know what logs or details would be helpful to share further.

Thanks in advance,
Rahul Chauhan

Hi Rahul,

I see that you're using the preview release of NCS v3.0.0. Unless there is any specific reasons for using the preview release. Could you try by following the documentation for a more stable, fully tagged release such as NCS v2.9.1?

Kind regards,
Andreas

Hi Andreas,

Thanks again for the suggestion.

I’ve used NCS v2.9.1 before, but it doesn’t support west zap-append or custom Matter clusters—so I moved to the v3.0.0 series.

I tested with:

• v3.0.0-rc1

• v3.0.0-preview1

• v3.0.0-preview2

But I’m still getting this error when launching ZAP or generating output:

This Error show

FATAL ERROR: command exited with status -6: /home/rahul/ncs/v3.0.0-rc1/modules/lib/matter/.zap-install/zap /home/rahul/nrf/template/src/default_zap/template.zap --zcl /home/rahul/ncs/v3.0.0-rc1/modules/lib/matter/src/app/zap-templates/zcl/zcl.json --gen /home/rahul/ncs/v3.0.0-rc1/modules/lib/matter/src/app/zap-templates/app-templates.json --tempState

It seems related to the ZAP environment or how zcl.json and templates are handled in these versions.

Is there a known fix or workaround?

Happy to share logs or files if needed.

Best,
Rahul Chauhan

Hi AHaug ,

We have tried with the NCS v3.0.0 and it seems like issue is still there. We have even tried to use zap tool with manufacturer_specific sample but we are getting below error. Can you please check with the Matter team?

Hi Bhavya,

Noted, thank you for verifying. I will bring it up with the Matter team ASAP

Kind regards,
Andreas

[AHaug]

Could you also share your zcl.json file? I would like to have a look at it and see if it somehow is missing something

Kind regards,
Andreas

Hi,

Both me and several of my colleagues have tried to reproduce the issue without any success. Here's the following steps we've used

1. cd nrf/samples/template
2. Copy  MyCluster.xml content from step 2 of the mentioned guide into a new file in the Template sample directory.
3. west zap-gui -j ./zcl.json --clusters ./MyCluster.xml

Could you triple check that you've followed these exact steps?

Kind regards,
Andreas
