Node-red version 1.2.7

Debian 10  
node-red-node-mysql version 0.1.3  
mysql 2.18.1

Hi

After updating the mysql node from 0.1.1 to 0.1.3 I get the following error in the log (after about 6 minutes of running fine) and NR restarts:

```auto

```

I've downgraded to 0.1.2 and the issue is gone.

Will post an issue to Github if necessary.

Regards
