MongoError: Mongodb does not provide binaries for versions before 4.2.1

[italosantana]

Open this issue, in case, you had this error when to run testing in this project.

Requested Version "4.0.5" is not available for "Debian 11"! Available Versions: ">=4.2.1"
    Mongodb does not provide binaries for versions before 4.2.1 for Debian 10+ and also cannot be mapped to a previous Debian release

In my case, I'm using debian 11 version. Sure, error tell me what to do...

<rootDir>/apps/server/test/environment/mongodb.js.

Check this in mondodb.js

const dbName = config.MONGO_URI_TEST.split('/')[3];

 // TODO - enable replset if needed
 // this.mongod = new MongoMemoryReplSet({
 this.mongod = new MongoMemoryServer({
   instance: {
     // settings here
     // dbName is null, so it's random
     dbName,
   },
   binary: {
  -------------->   version: '4.0.5',
   },
   // debug: true,
   autoStart: false,
 });
}

Change the version the error is inducing to which will work on your OS. In my case, using 4.2.1 running as well...

it is not necessary. this is a common compatibility error in mongo memory server, it only reports that it must change the binary version, where I put the arrow in the mongodb.js file. When you do that, you will see that the error will change and it will start to download the instance on your machine.
