Fix the 'multiple-value in single-value context' error by capturing all return values or ignoring extras with the blank identifier.
"multiple-value X in single-value context" error occurs because a function returns multiple values, but you are trying to assign them to a single variable without using the blank identifier.
// Incorrect: function returns (int, error)
x := someFunction()
// Correct: capture both values or ignore the error
x, err := someFunction()
// OR
x, _ = someFunction()
The "multiple-value X in single-value context" error happens when a function gives you two pieces of information (like a result and an error), but you only asked for one. It's like a waiter bringing you a meal and a bill, but you only have one hand to hold the plate. You must either take both items or explicitly tell the waiter you don't want the bill.
