Error: Property or field ‘id’ cannot be found on null

Explanation:

This error typically occurs when you are trying to access a property or field called ‘id’ on a null object. In most programming languages, null represents the absence of a value or an uninitialized object. When you try to access any property or field on a null object, it results in an error.

Example:

Let’s say you have the following code snippet in JavaScript:

    
    let obj = null;
    let id = obj.id; // Error: Cannot read property 'id' of null

In this example, the variable ‘obj’ is assigned a null value. When you try to access the ‘id’ property on the null object, an error is thrown since null does not have any properties.

To fix this error, you should ensure that the object is not null before accessing its properties or fields. You can use conditional statements or null checks to handle such cases.
