It is recommended to use the fmt.Errorf method with parameters instead of the errors.New method without parameters.

If using fmt.Errorf then formatting specifiers should be used instead of string concatenation. Either use appropriate formatting specifiers with fmt.Errorf or use errors.New with a concatenated string.
