I've attached a network capture of this happening with a Xpand 6.1 docker container. The reason appears to be an unexpected LOAD DATA LOCAL INFILE request that the connector is not ready to handle. I believe this should also be reproducible with any database proxy (e.g. MaxScale) that would convert a LOAD DATA INFILE request into a LOAD DATA LOCAL INFILE without the connector knowing of it.
