Another solution is to use the official MongoDB documentation on middleware. They explain why "this" does not refer to the document itself. You may try something in that sense:

   source.pre('findOneAndUpdate', async function(next) {
     const docToUpdate = await this.model.findOne(this.getFilter());
        //modify the appropriate objects
     docToUpdate.save(function(err) {
       if(!err) {
         console.log("Document Updated");
        }
     });
    console.log(docToUpdate); 
     // The document that `findOneAndUpdate()` will modify
       next();   
     });
