Upgrade to 3.2 breaks GridFS

While 3.1 works perfectly, 3.2.x for me gets:

TypeError: this.db.on is not a function
    at GridFSStorage._setDb (/Users/malix/Temp/nz/node_modules/multer-gridfs-storage/lib/gridfs.js:253:6)
    at MongoClient.connect (/Users/malix/Temp/nz/node_modules/multer-gridfs-storage/lib/gridfs.js:209:12)
    at connectCallback (/Users/malix/Temp/nz/node_modules/mongodb/lib/mongo_client.js:515:5)
    at /Users/malix/Temp/nz/node_modules/mongodb/lib/mongo_client.js:449:13
    at _combinedTickCallback (internal/process/next_tick.js:131:7)
    at process._tickCallback (internal/process/next_tick.js:180:9)

connectiing with:

import * as GridFsStorage from 'multer-gridfs-storage';
const storage = new GridFsStorage({
    url: config.secrets.uris,
    //...
});```

!?
