Exception generated by "findDocumentByKeyValue"

Question

I want to develop a logic which finds the document using "findDocumentByKeyValue" and if such document not found then i want to create the document. For this use case i need to write Document creation code in "onException" of "findDocumentByKeyValue" method. Now problem is whnever coding flow enters into the  "onException" connection gets lost with error "Should stop return ......Missed 3 beats" something like this. 

Is there any solution for this ??

Hi testDemo,

Greetings!!!!!!!!

Yes, you can create the Document in OnException callback method easily. but make sure it not be fall in loop. Please share your code so that I can validate why you are getting errors.

Let me know the details.

// My usecase is in doInBackground as below

As you are already using the async task, so I would like to suggest you to use sync api and do Exception handling else it will create thread inside other Thread

---

Can you suggest me some code snippets or references about Sync api to solve this problem

Storage storeData = storageService.insertJSONDocument(DBName,
                CollectionMeetings, jsonBody);
        System.out.println(storeData.getStrResponse());
        if (storeData.isResponseSuccess()) {
            ArrayList<Storage.JSONDocument> jsonDocList = storeData
                    .getJsonDocList();
            for (int i = 0; i < jsonDocList.size(); i++) {
                try {
                    response = new JSONObject(jsonDocList.get(i).getJsonDoc());
                   
            }
        }
