parseInt probably won't throw an error it'll just return isNaN

not good Like

    const groups = await pool.query(
      `
        select g.* from groups g
        left join attribute_groups ag on g.id = ag.group_id
        left join attributes a on a.id = ag.attribute_id 
        where a.id = ?
    `,
      [attribute.id]
    );

    const groups = await pool.query(
      `
        select g.* from groups g
        left join attribute_groups ag on g.id = ag.group_id
        left join attributes a on a.id = ag.attribute_id 
        where a.id = ?
    `,
      [attribute.id]
    );

when you say db success what do you mean?

I mean get valid results Actual rows not empty result [] or {}

Gghardin137

that's not an error that's just there's nothing that matches it's a valid end state so you'd just need to check if that's the value yourself
