So i‘m trying to deploy a function on openfaas based on arm architecture,but i failed.Can someone tell me how to solve it?

my kubernetes is based on arm,with kubernetes1.22.4

my faas-cli command:

faas-cli build -f ./add.yml 

the response code :

[0] > Building add. Clearing temporary build folder: ./build/add/ Preparing: ./add/ build/add/function Building: myw/add:latest with python template. Please wait..

Total build time: 0.54s Errors received during build: - [add] received non-zero exit code from build, error: The command '/bin/sh -c chmod +x /usr/bin/fwatchdog' returned a non-zero code: 1 

then can someone tell me the currect way to build a function with arm in openfaas,and why this happened,did i do someting wrong?
