[Vuejs]-What causes the duplicated key error in this Vue.js application?

✅

On your App.vue you defined props['todos'] and at the same time todos is defined in your data(). That might be the one causing the error.

Looks like you forgot to define dataIsLoaded in List.vue. It either needs to be defined in data or be a computed property.
