Cannot read properties of null (reading ‘writevalue’)

Explanation:

This error occurs when you try to read a property of a variable that is null or undefined. The error message specifically states that you are trying to read the property ‘writevalue’ of null.

Here’s an example to illustrate this error:

In the example above, the variable ‘someVariable’ is assigned the value ‘null’, which means it does not have any properties. Then, when you try to read the property ‘writevalue’ of ‘someVariable’, it results in an error because ‘null’ does not have that property.

To fix this error, you need to ensure that the variable is not null or undefined before attempting to read its properties. You can use conditional statements or null-checking techniques to handle such situations.
