I have a script with mock data stored in a variable named whatsHappeningItems, and I am trying to pass this data as a reference to a card component using v-for="whatsHappening in whatsHappeningItems". However, when I do this, I encounter the following error message:
[vue/valid-v-for] Custom elements in iteration require 'v-bind:key' directives.
const whatsHappening: {
title: string;
count: string;
}
Does anyone know why this error is occurring?
When using eslint, it may add code similar to the following:
<...
v-for="(whatsHappening, index) in whatsHappeningItems"
:key="index"
....
It appears that the problem was related to an eslint issue, as pointed out by Tachibana Shin
I had initially written this code snippet:
<...
v-for="whatsHappening in whatsHappeningItems" v-bind:key="whatsHappening"
....
Here is how my mock data was structured:
<...
<script setup>
const whatsHappeningItems = ref([
{
title: 'example',
count: 'example',
},
]);
</script>
....
After making some corrections, all errors were resolved and the issue seems to be fixed now.
