Nullable modifier cannot be used with a variable whose implicit type is 'Object'
A variable declaration includes the nullable type modifier (?), but does not specify a type or infer a type by assigning a value to the declared variable.
Error ID: BC33112
To correct this error
Specify a type when declaring the nullable variable. The type cannot be Object.
Assign a value when declaring the nullable variable. The type of the nullable variable will be inferred from the assigned value. The type of the value cannot be Object.
