After integrating MSGraphConnector and fixing all the errors it presents and running locally, I come across the following java error: Buildfile: C:\Users\c.correia\Documents\Mendix\App-main\deployment\build_core.xml compile: [javac] Compiling 329 source files to C:\Users\c.correia\Documents\Mendix\App-main\deployment\run\bin [javac] C:\Users\c.correia\Documents\Mendix\App-main\javasource\msgraphconnector\actions\custom\ExecuteHttpRequest.java:3: error: package org.apache.http does not exist [javac] import org.apache.http.HttpEntity;

Since it is a beta version for more than 2 years now, it seems like it is no longer maintained. I would reach out to the person who uploaded it and ask if this is still in development or if he has any advice.

Have you downloaded the dependent Community Commons module from the App Store? It should provide the missing Java file to fix this error.
