NextGen (Mirth) Connect & MongoDB java driver error

I am trying to configure Mirth Connect Server 3.10.1 (Java version: 1.8.0_181), to write FHIR JSON docs to MongoDB. I've followed instructions from this post and have these drivers in custom-lib/

  • bson-4.2.0.jar
  • mongodb-driver-3.9.1.jar
  • mongodb-driver-core-4.2.0.jar

My conf/dbdrivers.xml has an entry like this,

<driver class"org.mongodb.Driver" name="MongoDB" template="mongodb://localhost:27017/" selectLimit="" />

I've setup my Channel Destination with a JavaScript Writer Connector Type and used this JS,

var mongoClient = new Packages.com.mongodb.MongoClient("localhost", 27017);
var database = mongoClient.getDatabase("synthea");
var collection = database.getCollection("synthea");                   
var jsonDoc = JSON.stringify(connectorMessage.getEncodedData(msg));
var doc = Packages.org.bson.Document.parse(jsonDoc);

collection.insertOne(doc);
var myDoc = collection.find().first();
logger.debug(myDoc.toJson());

mongoClient.close();

return;

When I deploy the Channel, I am getting this error.

Can anyone tell me what this means?

Any help or guidance very much (and humbly) appreciated.

Solution

  • I have a feeling this is due to the mismatched driver versions. Version 3.9 has the method indicated in the error, but 4.2 does not.

    Once you get that sorted out, you are going to want to change this line

    var jsonDoc = JSON.stringify(connectorMessage.getEncodedData(msg));

    to this

    var jsonDoc = connectorMessage.getEncodedData();

    msg does not exist in a Javascript Writer, and connectorMessage.getEncodedData() does not take any parameters and returns a String. connectorMessage is an instance of ImmutableConnectorMessage from the Mirth User API.
