[Solved] Vue3.2 component computed Error: Write operation failed: computed value is readonly

<template>
	<component
        ref="formComponent"
        :is="formComponent"
    />
</template>

<script setup lang='ts'>
	const mapComp: any = {
	  Record
	};
	const formComponent = computed(() => {
	  return mapComp[route.params.type as keyof typeof mapComp];
	});
</script>

Then the browser reports two warnings

 

After modification:

<template>
	<component
        ref="formComponent"
		:is="mapComp[route.params.type as string]"
    />
</template>

<script setup lang='ts'>
	import {useRoute} from 'vue-router'
	const route = useRoute()
	
	const mapComp: any = {
	  Record
	};
	const formComponent = ref<string>(route.params.type as string);
</script>

At this point, the problem is solved
