No registered action found for name 'some custom action name'

hi, thanks for the reply,

Do you mean, I have to add the buttons in the domain as well, for the buttons were I used in the custom actions?

note: I am using API calls for each button. So is that is a reason for the problem cause?. because if I use a carousel with only one button with API call it works perfectly. but I’m facing this issue if I add more custom functions
