{
"errorId": 0,
"errorCode": "",
"errorDescription": "",
"taskId": "61138bb6-19fb-11ec-a9c8-0242ac110006"
}
Getting Results
After you have the taskId, you need to submit the taskId to retrieve the solution. Response structure is explained in getTaskResult.
Depending on the system load, you will get the results within the interval of 1s to 10s
