In this post, we will give you information about How to Fix ‘Query was already executed’ in Mongoose – onlinecode. Here we will give you detail about How to Fix ‘Query was already executed’ in Mongoose – onlinecode And how to use it also give you a demo for it if it is necessary.

Mongoose throws a ‘Query was already executed’ error when a given query is executed twice. The most common explanation for this is you’re mixing await and callbacks.(Fix ‘Query was already executed’ in Mongoose)

// Causes "MongooseError: Query was already executed" error. That's because Mongoose
// executes a query when it receives a callback _or_ when you 'await'. If you
// 'await' and pass a callback, this query executes twice.
await Model.updateMany({}, { $inc: { count: 1 } }, function(err) { /* ... */ });


// Causes "MongooseError: Query was already executed" error. This query executes
// twice. Once because of the callback, and once because of 'then()'.
Model.updateMany({}, { $inc: { count: 1 } }, function(err) { /* ... */ }).then(() => { ... });

The solution is to skip passing a callback.
You don’t need callbacks in Mongoose, because Mongoose supports promises and async/await.

await Model.updateMany({}, { $inc: { count: 1 } });
// or
Model.updateMany({}, { $inc: { count: 1 } }).then(() => { ... });

But I want to execute a query twice twice

If you’re absolutely sure you want to execute the exact same query twice, you can use clone()

let query = Model.findOne();

await query;

// Throws "MongooseError: Query was already executed" error.
await query;

// Works
await query.clone();
