MongoServerSelectionError: connect ECONNREFUSED localhost:27017

[deflexable]

after almost a day of debgging, i was able to fix it by:

1. updating mongodb to "^6.5.0"
2. changing from line 57 all the way to line 66 to this

        proms.push(dataAccessAdapter.ConnectToDb(
          dbName
        ).command({ collStats: collection.name })
          .then((stats) => {
            collection.stats = {
              count: stats.count,
              size: stats.totalSize
            };
          }));

i have up-to 75 collections in a database.

executing db.collection.stats() simultaneously at Promise.all for this amount of collections causes mongodb to crash and exit

changing to db.command({ collStats: collection.name }) fixes it

although this issue doesn't occur if you have 0 - 50 collections

db.collection.stats() has also been deprecated and removed
