MONGODB DRIVER

[HamedBahram]

Using Mongodb as my database, I encountered the following error, which is relating to defining write concerns and the deprecation of the used methods in next-auth:

2021-07-13T16:20:32.203Z e9c48700-94e8-49b4-bbfd-3a4863d427f3 ERROR (node:8) [MONGODB DRIVER] Warning: Top-level use of w, wtimeout, j, and fsync is deprecated. Use writeConcern instead.

Here is the recommended way of setting write concerns from Mongodb:

Write concern can include the following fields:

writeConcern : { w: 'majority', j: true, wtimeout: 1000 }

• the w option to request acknowledgment that the write operation has propagated to a specified number of mongod instances or to mongod instances with specified tags.
• the j option to request acknowledgment that the write operation has been written to the on-disk journal, and
• the wtimeout option to specify a time limit to prevent write operations from blocking indefinitely.

How can this be fixed?

which adapter are you using?

I would check our adapters repository https://github.com/nextauthjs/adapters

https://github.com/nextauthjs/adapters/tree/main/packages/typeorm-legacy here is the source code of that adapter. Can you spot the problem? If not, how could we verify that it is a problem with next-auth and not an integration issue between typeorm and MongoDB?

I didn't spot anything in next-auth source code! It is probably the typeorm integration with MongoDB. Here is what I found in typeorm repo <https://github.com/typeorm/typeorm/blob/master/src/driver/mongodb/MongoConnectionOptions.ts> setting connection option in the old way, which will be deprecated. The write concern: - readonly w?: string | number - readonly wtimeout?: number - readonly j?: boolean the correct way is to specify a writeConcern property as an object containing the above values like so: writeConcert: { w: 'majority', wtimeout: 1000, j: false } Kind Regards, *Hamed Bahram*

Then I suggest that you open an issue on their repository, there is nothing for us to do, unfortunately.
