chekbox component is not working on build version

[rahmatrhd]

I use checkbox widget through a FormBuilder component. It is working on development mode, but after I build the project when rendering the checkbox there was an error:

Uncaught Error: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.

Check the render method of `ForwardRef(InternalCheckboxGroup)`.
