How does this function returns null? is it because of the variable scope or execution time of the functions?
async function getBook() {
var book;
await libray.findONe({ cat: 1 }, {}, async (err, res) => {
await section.findONe({ secId: res.secI }, {}, (error, result) => {
book = result;
});
});
book = result;
}
return book;
}
Try this
async function getBook() {
const res = await libray.findOne({ cat: 1 });
const book = await section.findOne({ secId: res.secI });
return book;
}
I think the problem is that you are returning from the function before the async function finishes. so one convenient way to solve this is to make a callback function from the async function.
Sorry I am not a js guy so I can't actually post code but I think you got the idea..
