I need help, when calling a variable it returns a null value

I am experiencing an issue with handling null values in my application. Occasionally, when I try to access a variable or property that should contain a value, I receive a null value instead. This causes the application to crash or not function as expected. I need help identifying the cause of the null value and how I can fix it to prevent it from affecting the functionality of my application.
Extra: When I register, the data is shown in the database, but when I call it on the home screen it doesn’t show me anything.

If it’s crashing when trying to get a property that doesn’t exist, right-click on the get property of object block and then click show advanced block. Set a default value to return when the property is not found.
