Your StatefulSet declaration seems ok.
However, as you're using a volumeClaimTemplates, have you declared a PersistentVolume before applying your configuration ?

In order to use a volumeClaimTemplate, you need to be in the situation described in the official documentation. Especially this sentence :

This tutorial assumes that your cluster is configured to dynamically provision PersistentVolumes. If your cluster is not configured to do so, you will have to manually provision two 1 GiB volumes prior to starting this tutorial

The problem is I was leaving <> in connection string. You have to remove those for authentication to work.

Problem is that your replica set nodes are seen outside at ports 9x42 but those nodes internal (configured) addresses are 27017. Both those must be same.So, when you start mongod you must give --port parameter with same port number what is used at outside of container.

I had this same issue I resolved it by adding following keyword to mongos: --bind_ip_all

so change:

The replication set configuration is container to container so requires the internal address and port container:27017

Accepted values for Do function arguements are int64, float64, string or []byte .Since you passed a map it failed with error unknown type %T

Here is a reference to the respective code that does it
