Encountering an issue with the Duplicate() function in BoxLang. When Duplicate() is used to copy a struct that contains a variable with a null value, it throws a null pointer exception. This exception occurs only when the null value is inside a struct. If the null value is directly assigned to a variable and duplicated, the function works correctly.

Code Example:

local.testStruct = {
key1 = "value1",
key2 = javaCast("null", "") // Null value
};

// Attempt to duplicate the struct
local.duplicateStruct = Duplicate(local.testStruct);
