What is the Problem?

Model.deleteMany does not respect the writeConcern options

Code Example

I have a LogModel defined using

import { getModelForClass, modelOptions } from '@typegoose/typegoose';
@modelOptions({ schemaOptions: { writeConcern: { w: 0 } } })
export class Log {...}

export const LogModel = getModelForClass(Log);

the write concern here is to speedup the log write requests.

Now I would like to remove the logs inside a transaction with other models, and the error is:
Cannot have explicit session with unacknowledged writes

await withTransaction(async (session) => {
    ...other removal
    await LogModel.deleteMany({ user: user._id }, { session });
    ...other removal
});

I tried supply explicit write concern into the deleteMany query to override the setting in model, but same error occurs.

await withTransaction(async (session) => {
    ...other removal
    await LogModel.deleteMany({ user: user._id }, { session, writeConcern: { w: 'majority', j: true } });
    ...other removal
});

Do you know why it happens?

no

maybe check the mongoose log via mongoose.set('debug', true) before running your transaction

also if this really is not running properly, then this is a mongoose problem, not a typegoose one

Mongoose team confirmed and fixed this bug. Thanks.

for reference, i guess Automattic/mongoose#13592 is the one that was opened for this
