Line 17 in c667c4f

resolve( err )

The code here is reject but not resolve

return new Promise(( resolve, reject ) => {
    pool.getConnection(function(err, connection) {
      if (err) {
        resolve( err ) // reject( err )
      } else {
        connection.query(sql, values, ( err, rows) => {
          if ( err ) {
            reject( err )
          } else {
            resolve( rows )
          }
          connection.release()
        })
      }
    })
  })
