Cannot read properties of undefined (reading geoJson )

This error typically occurs when you are trying to access a property of an object that is undefined. In this case, it seems like you are trying to access the `geoJson` property of an object, but the object itself is undefined.

To fix this issue, you should ensure that the object containing the `geoJson` property is properly initialized before accessing it. You can use conditional statements or null/undefined checks to avoid accessing properties on undefined objects.

Here's an example of how you can handle this situation:

if (myObject && myObject.geoJson) {
  // Access the geoJson property here
  console.log(myObject.geoJson);
} else {
  // Handle the case when the object or geoJson property is undefined
  console.log("Object or geoJson property is undefined.");
}

By performing these checks, you can prevent the "Cannot read properties of undefined" error from occurring.
