Hi there,
this problems occurs when you send a request which contains an invalid request counter. Here I have an example of the json-object which is within an http-request:
{"head":{"requestCounter":11},"operations":[["set","w2",{"activeControl":"w11"}],["set","w11",{"selection":[3,3],"text":"ssa"}],["set","w2",{"activeControl":"w13"}],["notify","w13","Selection",{"button":1,"shiftKey":false,"ctrlKey":false,"altKey":false}],["set","w1",{"cursorLocation":[272,482],"focusControl":"w13"}]]}
When you look at the position , it contains the value . In case you want to send a request which is not fired by some user interactions on the UI, the requestCounter has to be increased by 1 for each request, you send to the server. Otherwise you don't get a correct response.
You could see the requestCounter as a protection for fuzzing attacks. Normally the requestCounter updates the values by itself but only when you have direct interactions with some GUI components like button-clicks etc.
I hope I could help you!
Best regards,
Aziz
