  1. Implement -fixEmptyArrays to force empty array [] instead of null

    … in JSON
    
    Golang issue: golang/go#27589
    
    This option will enforce server to encode nil slices as empty arrays in JSON.
    
    This is helpful mainly in JavaScript and TypeScript clients, where a response
    field of type array should never be assigned to `null` value..
    
    Example:
    
    func (s *Server) GetItems(ctx context.Context) ([]*Items, error) {
    	var items []*Item
    
    	// Will send {"items": []} in JSON response instead of {"items": null}.
    	return items, nil
    }
