The matter zap tool opens a. zap file, is error

[DoubleAmaing]

Please refer to the following image. Some clusters have warnings, may I ask what is missing from these?

I use D: ordinacsemi v2.4.1 nrf samples matter light_ Bulb's .zap

On the other hand, there is an error message stating 'Error: Unable to find cluster extension by component.';

I don't know where I made a mistake. Please help me, thank you

The main interface of Zap has the following prompt

• Check type contradiction in XML metadata for ColorControlOptions with type BITMAP8
• Check type contradiction in XML metadata for BarrierControlBarrierPosition with type INT8U

Do you install the ZAP tool by following the instructions in Matter tools -> Installing the ZAP tool?

You can ignore them which are implemented in endpoint-1. 

there is an error message stating 'Error: Unable to find cluster extension by component.';

How do you get the error? What did you modify? I could not reproduce it.

thanks you.

Yes, I have followed ZAP according to the official guidelines；

“'Error: Unable to find cluster extension by component.';”： The "notifications" in the screenshot below(I'm not sure if this prompt will affect anything)

but Endpoint 1 can be edited without any warnings;

According to the guidelines, I enabled on/off and temperature cluster

And I compiled according to the process, as follows:

But there is an error:

clang-format error: [WinError 2] 系统找不到指定的文件。

Which guidelines are you using? Could you provide the links?

You said you are using light_ Bulb's .zap in the original post, but seems you are building another sample in the log. 

Could you elaborate in more detail to help me reproduce the issue?

Hi，

links:

Adding clusters to Matter application — nRF Connect SDK 2.4.99 documentation (nordicsemi.com)

Matter tools — nRF Connect SDK 2.4.99 documentation (nordicsemi.com)

I downloaded the 2.4.1 SDK through nRF connect for desktop;

Open the. zap file according to the link above;

Then, I use light_ Switch. zap to perform zap compilation, I did not perform   any changes to the light_Switch.zap.

Hi,

I  can't find MatterPostAttributeChangeCallback() in the file src/zap generated/callback stub. cpp ；why?

I searched globally for this function and found that it was in another file

Please run the command `pip install clang-format` to fix the error.

Thanks for the report. We will fix it. You can refer to the example for the implementation.

thank you.

I have installed clang format and updated it to the latest version, but it still prompts this error.

May I ask if this error has an impact on adding a cluster? Will it affect the operation of the program?

Hi, 

You run the wrong command instead of `pip install clang-format`.

After running `pip install clang-format`, I don't get any errors.
