VueX - Dispatch action in a different module from an action

If you don't have payload to pass, then you need to send the second parameter as a null like:

dispatch('ride/clearUserData', null, { root: true })

Your usage of dispatch() is incorrectly passing { root: true } as the 2nd argument, which is intended for the payload. Options should be 3rd:

// dispatch('ride/clearUserData', { root: true }) // FIXME: options passed as payload
dispatch('ride/clearUserData', null, { root: true })
