I was able to do it with
var myStringArray= getPhotos.data.FullUrl;
var arrayLength = myStringArray.length;
//async function go() {
for (var i=0; i <arrayLength; i++) {
getBinaryImageUrlOneDrive.trigger({
additionalScope :{
imageURL: getPhotos.data.FullUrl[i]
}
}),
downloadPhotosOneDrive.trigger({
additionalScope: {
imageName: getPhotos.data.PhotoId[i]+'.jpg',
imageCustomer: tableCustomer.selectedRow.data.Customer
}
});
}
