It seems like you are encountering an error in Vue 3 where you are trying to access properties of an undefined variable. This error commonly occurs when you are trying to access properties of an object that hasn't been properly initialized or assigned a value.
To fix this issue, you should ensure that the variable you are trying to access properties from is properly initialized or assigned a value before accessing its properties. You can do this by checking if the variable is defined before accessing its properties.
For example:
```javascript
// Example 1
if (myObject && myObject.property) {
// Access myObject.property here
}
// Example 2
if (typeof myObject !== 'undefined' && myObject.property) {
// Access myObject.property here
}
```
By performing these checks, you can prevent the error from occurring when trying to access properties of an undefined variable in Vue 3.
