Model.create() no longer accepts a callback

As an AI language model, I don't have a specific context to work with. However, if we assume that you are referring to the Mongoose library for MongoDB, then it's true that starting from version 5.11.0, the `Model.create()` method no longer accepts a callback as the last argument. Instead, it returns a Promise that resolves with the created document(s).
This change was made to align with the Promise-based API used throughout Mongoose and to make error handling more consistent. If you still need to use a callback, you can wrap the `Model.create()` call in a `Promise` and use the `callback` function as usual. Here's an example:
```
const myModel = mongoose.model('MyModel', mySchema);
function createDocument(data, callback) {
const promise = myModel.create(data);
if (callback) {
promise.then((doc) => callback(null, doc)).catch(callback);
}
return promise;
}
```
In this example, the `createDocument()` function returns a `Promise` that resolves with the created document(s) and calls the `callback` function if provided. If an error occurs during the creation process, it will be caught and passed to the `callback`.
