Strange code fragment

What should be done?

I found two 'if' statements have identical conditions. The first 'if' statement contains function return, making the second 'if' redundant, or the code contains a logical error.

curArr, ok := cursorsV.(wirebson.AnyArray) if !ok { msg := fmt.Sprintf(required parameter "cursors" has type %T (expected array), cursorsV) return nil, lazyerrors.Error(mongoerrors.NewWithArgument(mongoerrors.ErrBadValue, msg, command)) }

cursors, err := curArr.Decode() if !ok { return nil, lazyerrors.Error(err) }

A strange piece of code was found with PVS-Studio analyzer inside the msg_killcursors.go file on line 61.
