Lucee 6.0 - Docker - Mongo - Component has no function with name [size]

dev support
1

I’ve been working with this docker container
FROM lucee/lucee:6.0.0.524-SNAPSHOT-light-nginx-tomcat9.0-jdk11-temurin-jammy
including this Mongo driver in the cfconfig.json

		{
			"id": "E6634E1A-4CC5-4839-A83C67549ECA8D5B",
			"name": "MongoDB Datasource and Cache",
			"version": "3.12.13.0"
		},

loading the mongo connection to server scope on app startup
<cfset server[“mongo”] = MongoDBConnect(“dbname”, “mongodb://dbserver:dbpass@servename/dbname”)>

db finds seem to work fine, but any save or insert throws an exception with different components

server[arguments.mongoDatabase][arguments.mongoCollection].save(thing);

Component [path.to.the.component.we.want.to.save] has no function with name [size]

We have had save() working with the same method for quite awhile with Lucee 5.
Any ideas? thanks
