Javascript await in imbricated loop error [duplicate]

Question

I'm trying to understand to to imbricate loops in javascript and call an imported async function from an async script and I get an error. It seems like ReadinglogManager.getReadingLogForAPeriod cannot be call with await?

Main code:

var myfunction = async function(req, res, next){
students.forEach(function(s) {
            
            dateobj.forEach(function(d) {
               console.log('Date: '+d.toString())
                let st= new Date();
           
                const rl = await ReadinglogManager.getReadingLogForAPeriod(st,s.uid );

            });

        });
}

From ReadinglogManager:

var getReadingLogForAPeriod = async function(start_date, student_uid){
   
    let db = DatabaseManager.fs.firestore();
    let dataset = [];
    let snapshot = await db.collection('ReadingLog').where('date', '>=', start_date).where('student_uid', '=', student_uid).get();
  //  dataset = await DatabaseManager.snapshot_to_resultset(snapshot);
    await snapshot.forEach(doc => {
        let tdoc=doc.data();
        tdoc.uid=doc.id;
        console.log("DOC: "+JSON.stringify(tdoc));
        dataset.push(tdoc);
    });
    return Promise.resolve(dataset);
}

Thanks
