How to avoid [vue/no-parsing-error] Parsing error: duplicate-attribute?

Question

Vue.js

It is assumed that the component will have data in the form of such hashes:

<template>
    <settings
        :mod="'mod'"
        :ready_site: {
                old_price: 1,
                price: 1100,
        }
        :license: {
                old_price: 20,
                price: 200,
                title: 2,
        }
        :hosting: {
                old_price: 30,
                price: 300,
                title: 4,
        }
</template>

When creating such a construct, I get an error from the linter:
[vue/no-parsing-error]Parsing error: duplicate-attribute.
[vue/no-duplicate-attributes]Duplicate attribute 'old_price:'.
and about the same, but swearing at the same keys in the hash.
If I need the data in the form of hashes with keys, then how to avoid the error above?

Answer 1

:license="{
  old_price: 20,
  price: 200,
  title: 2,
}"

Well, the rest are the same.
