[Andres Martinez Gotor]

the error is hiding in the compile init container. You can get the details of the error executing:

kubectl logs get-go-8885d7974-9rqn7 -c compile

@andresmgot thank you, using this method, I found a problem and solved the problem.

kubectl logs get-go-8885d7974-9rqn7 -c compile
rm: cannot remove '/kubeless/go.mod': No such file or directory

need --dependencies when deploy a function.
