mongoose error : query already exists...

Comment

// Mongoose 6.6.3
// Query.prototype.clone()
// Returns:
// «Query» copy
// Make a copy of this query so you can re-execute it.

// Example:`enter code here`
const q = Book.findOne({ title: 'Casino Royale' });
await q.exec();
await q.exec(); 
// Throws an error because you can't execute a query 
twice

await q.clone().exec(); // Works
