can not switch parent frame in chrome

[chronos2015]

When trying to return to the parent frame in chrome, the following error occurred.

failed to switch to parent frame: request unsuccessful: invalid argument: missing command parameters

So when I changed the code in the following file and executed it, it worked fine.

..\github.com\sclevine\agouti\api\session.go
before
func (s *Session) FrameParent() error {
return s.Send("POST", "frame/parent", nil, nil)
}

after
func (s *Session) FrameParent() error {
request := struct {
ID interface{} json:"id"
}{nil}
return s.Send("POST", "frame/parent", request, nil)
}

Thanks,
