What problem are you facing?

I'm trying to configure CSFLE on the community edition MongoDB server with nodeJs and node-mongodb-native driver. From the documents, I gather that explicit encryption with automatic decryption is possible in the community edition and it doesn't require the mongocryptd process if we pass the 
bypassAutoEncryption: true option in autoEncryption Object.
But while doing so, the MongoDB client throws an expectation and exits.

'MongoServerSelectionError: connect ECONNREFUSED 127.0.0.1:27020'

Note: **I am able to use/configure explicit encryption with automatic decryption on Mongo shell.

What driver and relevant dependency versions are you using?

nodeJs: v14.15.1
mongodb-client-encryption: v1.2.6
mongodb: v4.1.1
MongoDB server(community edition): 4.4.8
_MongoDB shell: v4.4.8_
 
OS: Tried on
macOS(silicon): 11.2.3
AmazonLinux2
 
As of now, I'm using the local key store for the master key

Steps to reproduce?

 
```
const secureClient = new MongoClient('mongodb://xxxxx:xxxx@xxxxxx:27017/xxxxxx', {
useNewUrlParser: true,
useUnifiedTopology: true,
autoEncryption: {
bypassAutoEncryption: true,
keyVaultNamespace,
kmsProviders,
extraOptions:

,
}
});
```

```
const connect = async () => {
try

catch (err)

};

connect();
```
