MongoDB JDBC driver for DB Connect 3.1.2 not working

[kc64645]

How do I install jdbc drivers for mongodb? I copied jar file mongo-java-driver-3.7.1.jar to $SPLUNK_HOME/etc/apps/splunk_app_db_connect/drivers directory and created db_connection_types.conf but I still see below errors. My DB connect version is 3.1.2. Thanks

db_connection_types.conf
[mongodb]
displayName = MongoDB
serviceClass = com.splunk.dbx2.DefaultDBX2JDBC
jdbcDriverClass = mongodb.jdbc.MongoDriver
jdbcUrlFormat = jdbc:mongo://host:port/database
port = 27017
ui_default_catalog = $database$

Error-
action=load_drivers Can not load any driver from files [$SPLUNK_HOME/etc/apps/splunk_app_db_connect/drivers/mongo-java-driver-3.7.1.jar]

Check this:

Try to use this driver: mongodb_unityjdbc_full.jar

It seems to work for me.
