I have tried to insert a sample document using _bulk API on opensearch console and it worked, below is the thing I had tried over opensearch, which worked
POST _bulk
{"index":{"_index":"contacts"}}
{"name": "name","phone" : "11111111","created_at" : "2021-12-21T12:12:59","updated_at" : "2021-12-21T12:12:59","id": 101}
