Hi, everyone, I have in trouble about `short variable declaration`
Here is my codes snippet
package utils
import "os"
type FileController struct{
file *os.File}
func (c *FileController)OpenFile(path string)error{
c.file, err := os.OpenFile(path,os.O_CREATE | os.O_RDWR,0755)
//return some value these}
c.file have been declared, but err not.
>From golang spec docs

> same block (or the parameter lists if the block is the function body) with
> the same type, and at least one of the non-blank variables is new.
My codes snippet should works, but `GolandIDE` tell me "unresolved
reference 'err' "

It's a bug about Goland IDE or just I'm wrong?
