Error in daily.log

Every day in the daily.log I get the following message :
No cached PeeringDB data found, sleeping for 17 seconds
SQL Error! SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ‘)’ at line 1 (SQL: DELETE FROM pdb_ix WHERE pdb_ix_id NOT IN ()) (SQL: DELETE FROM pdb_ix WHERE pdb_ix_id NOT IN ())
/opt/librenms/includes/functions.php:2403

Do I need to do something?

Run validate.php and post the output. Please

[root@librenms librenms]# ./validate.php
