This error message suggests that the property 'showModal' is undefined in the component, and therefore cannot be accessed in the 'addMusicType' method. It is possible that the property was not properly initialized or passed down as a prop from a parent component. Double check the component's code and make sure that all necessary properties are properly defined and passed down.
