Getting "Failed to find command GUBP" when running AutomationTool

I am attempting to follow the answer on this question: and make a build of the engine. However when running the command

RunUAT.bat GUBP -Node=GatherRocket -TargetPlatforms=Win32+Win64 -NoDDC -CleanLocal

I receive the following error:

Program.Main: ERROR: AutomationTool terminated with exception: AutomationTool.AutomationException: Failed to find command GUBP

I couldn’t find this error anywhere online to see what I may be doing wrong.

Check this answer out. I was having the same issues and it just looks like the phrasing of how this is done has changed quite a bit since the post you linked was written.

Here’s the documentation detailing the new syntax:
