MySQL Client 5.7.31 loses connection with BI Connector (5.7.30)

I’m trying to evaluate MongoDB BI Connector. I got it up and running but encountered an issue that others and probably the MongoDB devs should know about.

Trying to use the latest (ATM) MySQL client 5.7.31 leads to receiving the error ERROR 2013 (HY000): Lost connection to MySQL server during query on the first query you will try once connected to a database. Using version 5.7.30 works.

MongoDB v4.4.0
MongoDB BI Connector v2.14.0
Running in Docker with a Ubuntu Bionic base image.
