Error in created hook (Promise/async): "TypeError: Cannot read properties of undefined (reading 'forEach')" found in

The error you encountered is likely related to accessing properties of an undefined object using the `forEach` method. This error commonly occurs when you attempt to iterate over an array or object that is undefined or null.
To resolve this issue, you should check if the object is defined before trying to access its properties. Here's an example of how you can handle this error:
```javascript
if (myArray && myArray.length > 0) {
myArray.forEach((item) => {
// Do something with each item
});
}
```
In this code snippet, we first check if the `myArray` object is defined and has a length greater than 0 before iterating over its elements using `forEach`. This prevents the error from occurring when the array is undefined.
Make sure to apply similar checks to any other objects or arrays that you are using in your code to avoid similar errors.
