Possible Null pointer dereference

[stp32]

The code in Admin.Admin.getSupplierNames() contains a possible null pointer dereference where the variable "data" is dereferenced without first checking if it is null. This can cause potential crashes when the application is ran.

To reproduce:

• Go to Admin.Admin.getSupplierNames() in the src/main/java folder
• Go to line 834 and locate the "size" initialization
• Identify that it doesn't check if "data" is null before using it

Expected: Variables should be checked if they're null before dereferencing to avoid potential NullPointerExceptions and ensure stability and reliability
Actual: The code doesn't check for null which may result in a crash under certain circumstances.
