This is a failed check for a null terminator byte of a BSON string in the document that the driver is attempting to decode.  It indicates that the document is corrupted.

Would you be able to provide a dump of the collection that you're querying?  If so, let me know and if necessary we can provide a secure location for which to upload the data.

Regards,

Jeff
