I am having a simple code, but having no clue of why the for loop is running once. with the data I am having, it should run 7 times (imax = 7). The code in yellow, never run
Any idea of why the for loop stop running.

$w.onReady(async function () {

    let s2 = wixData.query("integrityBooking")
        .isEmpty("execTime")
        .find()
        .then(async (results) => {
            let resCount = results.totalCount;
            if (resCount > 0) {
                let itgTbl = await results.items;

                let imax = itgTbl[0].bookObj.rowCount;
                console.log("#itération= " + imax);

                for (let index = 0; index < imax; index++) {
                    let exec = await itgTbl[index].execTime;
                    iRow = await itgTbl[index].iObj;
                    bRow = await itgTbl[index].bObj;
                    bookRow = await itgTbl[index].bookObj.rows;

                    let tblRow = {
                        "fromDt": bookRow[index].fromDt,
                        "toDt": bookRow[index].toDt,
                        "chalet": bookRow[index].chalet,
                        "loginEmail": bookRow[index].loginEmail
                    }
                    tbl[index] = await tblRow;
                    await $w('#table1').updateRow(index, tblRow);

                }
                await console.log("tbl row count = " + tbl.length);
            }
        })
        .catch((err) => { return (err) });
});
