when I change mysql version to 8.0.18, the dashboard views can’t work normally. It’s ok when mysql version is 5.7.29.
error message(visits over time module of dashboard page):
SQLSTATE[HY000]: General error: 3750 Unable to create or change a table without a primary key, when the system variable ‘sql_require_primary_key’ is set. Add a primary key to the table or unset this variable to avoid this message. Note that tables without a primary key can cause performance problems in row-based replication, so please consult your DBA before changing this setting. - in plugin Goals
