Remove deleteMany not working

[gmahe]

Looking at https://github.com/db-migrate/mongodb/blob/master/index.js#L337 the deleteMany method is not going to work.

We check if options is an array if(util.isArray(options)) and then add it in the query.

case 'remove':
  // options is the records to insert in this case
  if(util.isArray(options))
    db.collection(collection).deleteMany(options, callbackFunction);
  else
    db.collection(collection).deleteOne(options, callbackFunction);
  break;

The issue is filter from deleteMany(filter) is expected to be an object and not an array and will return an error: MongoError: BSON field 'delete.deletes.q' is the wrong type 'array', expected type 'object'

Here the code I was using:

db._run("remove", "pets3", { id: "003" }, callback); // This removes one entry.
db._run("remove", "pets3", [{ id: "003" }], callback); // This fails obviously.

// This code works and it's using directly the mongo instance.
const getDbInstance = await db._run("getDbInstance");
getDbInstance.collection("pets3").deleteMany({ id: "003" }); // This removes every entries.
getDbInstance.close();
