Info
Create a shard collection with key that isn't _id. $merge writes will send things to the DLQ with:
{
_id: ObjectId("651d8464f0b07ba2ac0ce8a3"),
_stream_meta:
{ timestamp: ISODate("2023-10-04T15:27:32.278Z") }
,
errInfo: {
reason: 'Failed to process an input document in the current batch in MergeOperator with error: Failed to target upsert by query :: could not extract exact shard key: generic server error'
}
}

Still need to figure out a proper fix for this. But possibly the error goes away if we specify the shard key in $merge.on. Confirming this. It also seems like server team recently worked on making this work even when the shard key is not specified in the incoming write. But it seems more efficient to always specify shard key for sharded collections.
