How to validate route parameter in Nuxt?
Your validate method must return a boolean:
async validate({ params, store}) { // await operations return true // if the params are valid return false // will stop Nuxt.js to render the route and display the error page}see official documentation: https://nuxtjs.org/api/pages-validate#the-validate-method
async validate({ params, store }) { return await store.dispatch(types.VALIDATE_PARAMS_ASYNC, params.id)}
