deno_mongo uses replica information from primary instead of URL

We have a replica set on MongoDB configured with hosts set in the /etc/hosts file which don’t exist on our development machines. When using a URL with the actual domains that are public, deno_mongo uses the information from the primary server instead of the URL. This is not the behaviour we get with Node’s MongoDB or with MongoDB Compass (which both use the servers in the connection URL).

Until this issue is fixed, use this as a temporary solution (Windows only):

1. Open C:\Windows\System32\drivers\etc\hosts in a text editor of your choice
2. Add your hosts at the bottom of the file like this:

IP HOST
IP HOST2
IP HOST3

1. Save the file, run ipconfig /flushdns in a terminal
2. Try again, if it doesn’t work try restarting the terminal
3. Enjoy!

I have the same problem also without replica. Is it possible to set the “moongose” option { useUnifiedTopology: true } in the connection?
