I wonder why you either forgot or purposely omitted to import the vee-validate components, it's really mind-nerving especially when the user is copy pasting your code in whole for trial then will get error whether in nuxt or vue and has to come back and add the imports... there's no justification and I'm not gonna argue just merge it...
