The too many arguments to return error in Go typically occurs when you are “returning more values from a function than specified in its signature.”
To fix the too many arguments to return error in Go, “ ensure that the number of values you are returning from a function matches its signature.“
Reproduce the error
Here’s an example of a function that causes the “too many arguments to return” error.
package main
import "fmt"
func example() int {
a := 1
b := 2
return a, b
}
func main() {
result := example()
fmt.Println(result)
}
Output
too many return values
How to fix it?
To fix the error, update the function’s return type signature to match the number of values you return. In this example, you can return a pair of integers by changing the return type to (int, int).
package main
import "fmt"
func example() (int, int) {
a := 21
b := 19
return a, b
}
func main() {
result1, result2 := example()
fmt.Printf("Result 1: %d, Result 2: %d\n", result1, result2)
}
Output
Result 1: 21, Result 2: 19
Handle the returned values properly and update both the function definition and the function call.
That’s it!
