This error occurs when you try to access a property of an undefined or null value in your Vue component's render function. The error message suggests that you are trying to access the 'type' property of an undefined object.
To fix this error, you need to ensure that the object you are trying to access is not undefined or null before accessing its properties. You can use conditional rendering to check if the object exists before rendering it. For example:
```
<template>
<div>
<div v-if="myObject">
<p>{{ myObject.type }}</p>
</div>
<div v-else>
<p>My object is undefined or null.</p>
</div>
</div>
</template>
<script>
export default {
data() {
return {
myObject: undefined
}
}
}
</script>
```
In this example, we use a v-if directive to check if myObject is defined before rendering it. If it is undefined, we show a message indicating that the object is undefined or null.
