This error typically occurs when you attempt to read properties of an undefined value. In this case, it seems like you are trying to access the `prototype` property of an undefined object.
To fix this error, you should first ensure that the object you are trying to access is defined and not null. You can use conditional statements or null/undefined checks to handle such cases and avoid accessing properties on undefined values.
Here's an example of how you can handle this error:
```javascript
if (myObject && myObject.prototype) {
// Access properties or methods on myObject.prototype here
} else {
// Handle the case when myObject is undefined or null
}
```
Make sure to check the code where this error is occurring and verify if you are properly initializing or assigning values to the object before accessing its properties.
