Answer 1

It means the variable on which the method get is called is undefined instead of being an object that accepts the method.

Look at the line number given by the error message (in the file given by the message). If the error is in a module, and you don't see where the variable should have been initialized, then put use diagnostics; at the top of the script after your use strict; and use warnings; so you get a stack of the method/function calls at the point of error.
