## @qp-mongosh/async-rewriter2
#### `ASYNC-10012`
Signals the use of a Mongosh API call in a place where it is not supported.
This occurs inside of constructors and (non-async) generator functions.

Examples causing error:
```javascript
class SomeClass {
  constructor() {
    this.list = db.coll.find().toArray();
  }
}

function*() {
  yield* db.coll.find().toArray();
}
```

**Solution: Do not use calls directly in such functions. If necessary, place these calls in an inner 'async' function.**
