Debugging mySQL Error

[drtech]

I am trying to figure out what this error is from. As the previous post, I setup a new lxc container running ubuntu 18.04 and mysql 5.7.25 instead of my longtime VM server running ubuntu 14.04 and mysql 5.5.62. Now I am getting this error: Any ideas how to help with this? Do I need to change sql_mode-only_full_group_by to something else? OD 18.2.18

Unhandled exception: Expression #2 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'opendental.plannedappt.ItemOrder' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

Modify the sql_mode parameter to either a blank string or NO_AUTO_CREATE_USER.
