Swarm: Remote Agents not Building Light

We have a dedicated server to build light and the Swarm Agent configuration is pass down to others PC via Perforce, so anyone can just run the Swarm Agent and connect to the coordinator. We recently updated to 4.21 and this setup stopped working, as it was looking for the following files;
AutoReporter.exe
AutorReporter.exe.Config
AutorReporter.XmlSerializers.dll

I was able to find these files but from a previous build 4.19, as the files were not being built when compiling the project. My question is,

  • How do I build AutoReporter.exe or where can I download it?

Below, excerpt from the Swam Agent log.
