Now that I fully understand the error and safe updates in MySQL, I have
fixed the real problem, which was to update the stored procedure with
delete statements that reflect all columns in the row to delete.
delete from <table1> where id not in (
select id from <table2>);
Modified, working statement:
delete r.* from table1 r
left join table2 a
on r.id = a.id
where a.id is NULL ;
