The test session doesn’t have any pending postbacks to send.
Declaration
static var noPendingPostbacks: SKAdTestError.Code { get }Discussion
This error occurs if you call flushPostbacks(responses:) before adding a postback to the test session (SKAdTestSession). To avoid this error, call SKAdTestPostback to create a test postback, and setPostbacks(_:) to add the test postback to the test session before calling flushPostbacks(responses:).
