autoIndex error with tungus and mongoose ~V4

[thakerng]

We got the message error when we executed the example script with mongoose v4.0.2

/node_modules/mongoose/lib/model.js:800
      (this.schema.options.autoIndex === null && this.db.config.autoIndex)) {
                                                               ^

Happens also with Mongoose 3.9.7, but not with 3.8.22

[ChrisTerBeke]

Same here, works in 3.8.22, not in 4.0.4

[sergeyksv]

Mongoose 4.x uses mongodb driver 2.x which has sensitive amount changes for API and untill TingoDB will get 2.x API compatibility module we'll not be able to support Mongoose 4.x

A workaround is to add a config object field in connections, see
