@dhrubo-os , After inserting data into a dummy index, if I immediately run the test cases to train model, I keep seeing an error No document found. If I include a sleep for 2 seconds or so, its not causing any problem. I used opensearchpy.helpers.bulk to insert the data. Does OpenSearch core insert data asynchronously? Do i need to put a check to see if the data in actually finished inserting into opensearch?

Test is failing. I checked this is not from the model uploading, this is related to your test.
