Error "Assignment to read-only properties is not allowed in strict mode" in IE11

[joonseolee]

I used v-jsoneditor component in my website.
it works on Chrome, Safari or even IE11.
But when I write a not validated json then it didn't show any alert message in IE11. (Working on Chrome, Safari)
How can I solve the problem?

Here is my code.

<template>
  <v-jsoneditor
                v-model="config"
                :options="options"
                :plus="false"
                height="800px"
                style="width: 800px;"
  />
</template>

and the error message in console.
