is thrown by the following code:
final UUID id = UUID.randomUUID();
final double frequency = 8_000.0 + ( 10_000.0 * Math.random() );
final double startSec = 100*i;
final double startNano = 10*i;
final double endSec = startSec + ( 100*i );
final double endNano = startNano + ( 10*i );
final double latitude = ( 180.0*Math.random() ) - 90.0;

//_collection.insertOne( track );
_collection.updateOne(
trackID,
track,
new UpdateOptions().upsert( true ));
The commented code _collection.insertOne( track ); executes fine.
Why the insert is fine when the "upsert" is not?
Sagar Veeram :
updateOne for updating document fields using update operators. You need replaceOne which takes the replacement document.
_collection.replaceOne(
trackID,
track,
new UpdateOptions().upsert( true ));
