Which mongoose query fails using async await - node.js

Question

I have a small requirement.
I am trying to add documents into 2 different collections as shown below. In the below code, **Test1_Model** and **Test2_Model** are Mongoose Models in Node.js.
try {
const test1 = new Test1_Model({ name: "Dummy" });
const saveTest1 = await test1.save();
const test2 = new Test2_Model({ field: "Something" })
const saveTest2 = await test2.save();
} catch(err) {
console.log(err);
}
Now the requirement is to know that which of the above mongoose query returned an error and which one completed successfully. Yes, if test1.save() fails then test2.save() will not execute only but there can be a situation that test1.save() completes but test2.save() fails. So the aim is to know that exactly which of the query failed.
The above problem can be solved by replacing async/await into Promise handling using .then() and .catch(). You can find that solution below.
try {
const test1 = new Test1_Model({ name: "Dummy" });
const saveTest1 = test1.save().then().catch(err => {
throw new Error('Test1 Failed');
});
const test2 = new Test2_Model({ field: "Something" })
const saveTest2 = test2.save().then().catch(err => {
throw new Error('Test2 Failed');
});
} catch(err) {
console.log(err);
}
This solves the problem but the aim is to know that by using async/await, can we do something like this.
Thanks.

You can create a wrapper for every promise and throw an error or pass data from it.
const promiseHandler = (promise) => {
return promise
.then(data => ([data, undefined]))
.catch(error => Promise.resolve([undefined, error]));
}
try {
const test1 = new Test1_Model({ name: "Dummy" });
const [saveTest1, error] = await handle(test1.save());
if (error) throw new Error(`Error is on saveTest ${error}`)
const test2 = new Test2_Model({ field: "Something" })
const [saveTest2, error] = await handle(test2.save());
if (error) throw new Error(`Error is on saveTest2 ${error}`)
} catch (error) {
console.log(error)
}
