We are in the process of moving from a single replica set to a sharded database. After the converstion, we've started intermittently seeing this error:
TypeError: Cannot read property 'nextBatch' of undefined at Response.parse (/usr/src/app/node_modules/mongodb-core/lib/connection/commands.js:488:32) at /usr/src/app/node_modules/mongodb-core/lib/connection/pool.js:564:19 at authenticateStragglers (/usr/src/app/node_modules/mongodb-core/lib/connection/pool.js:516:16) at Connection.messageHandler (/usr/src/app/node_modules/mongodb-core/lib/connection/pool.js:552:5) at emitMessageHandler (/usr/src/app/node_modules/mongodb-core/lib/connection/connection.js:309:10) at Socket.<anonymous> (/usr/src/app/node_modules/mongodb-core/lib/connection/connection.js:452:17) at Socket.emit (events.js:182:13) at addChunk (_stream_readable.js:283:12) at readableAddChunk (_stream_readable.js:264:11) at Socket.Readable.push (_stream_readable.js:219:10)
Important details:
- These errors only occur on the one collection that is actually being sharded.
- The initial rebalance is still under way (looks like it will take many days to complete)
- The queries that are failing are against a 2dsphere index
- The queries that are failing are using the following settings
- `raw: true`
- `noCursorTimeout: true`
- `batchSize: 500`
- Mongo v3.6.3
- Node driver v3.0.10
- Node v10.4.1 (running on alpine)
