Kindly explain the change you had to make, and what problem it will solve.

I assume package.json change is done by mistake.

Will it still work with older mongo versions?

[akshay9502]

Mongoose version: 5.6.7 mongo: 4.0

in mongodb-backend, get function the select as the second parameter does not deselect _bucketname, thus in roles we even get _bucketname as role name

[akshay9502]

as it does not deselect the _bucketname, we get the "_bucketname" in the role names

[akshay9502]

yes it will work in the older versions as well
