pymongo.errors.NotMasterError: node is not in primary or recovering state, full error: {'errorLabels': ['ResumableChangeStreamError'], 'topologyVersion': {'processId': ObjectId('6051aeef70b908f4d4aa6594'), 'counter': 0}, 'operationTime': Timestamp(0, 0), 'ok': 0.0, 'errmsg': 'node is not in primary or recovering state', 'code': 13436, 'codeName': 'NotPrimaryOrSecondary', '$clusterTime': {'clusterTime': Timestamp(0, 0), 'signature': {'hash': b'\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00', 'keyId': 0}}}

To do that run mongo in your mongo_db container and execute the command bellow

rs.initiate()
