Cannot read properties of null (reading ‘useref’)

by

This error “cannot read properties of null (reading ‘useref’)” occurs when you are trying to access a property called ‘useref’ on a null object. This typically happens when you try to access a property on an object that has not been properly initialized or created.

To fix this error, you need to make sure that the object on which you are trying to access the ‘useref’ property is not null. You can do this by checking if the object exists or is defined before accessing its properties.

Here is an example that demonstrates how to avoid this error: 


      // Check if the object exists before accessing its property
      if (myObject && myObject.useref) {
         // Access the useref property
         console.log(myObject.useref);
      } else {
         console.log("myObject or myObject.useref is null or undefined.");
      }

In the above example, we first check if the ‘myObject’ variable exists and then check if it has the ‘useref’ property. If both conditions are met, we can safely access the ‘useref’ property without encountering the “cannot read properties of null (reading ‘useref’)” error.

By performing these checks, you can prevent the error from occurring and handle any potential null or undefined values gracefully in your code.
