BTSTask RemoveApp Gives Object Reference Error

Question

I have a BizTalk 2013r2 app with a receive location that uses the codeplex scheduled task adapter with a custom task.

If I try to remove the app using "BTSTask RemoveApp -ApplicationName:MyApp" from an admin elevated command line window, then I get the following error:

Error: Error while removing application "MyApp". Error: Could not validate TransportTypeData, Address or Public Address properties for Receive Location 'SharePoint.Sport sTimetable.Receive.SiteTimetable-Schedule'. Object reference not set to an instance of an object.

However, if I right-click the app in the BizTalk admin console and select Delete then it gets deleted no problem.

Any ideas how to fix this - there are no clues in the event log?

I switched from BTSTask to BTS Powershell, that's maybe a (workaround) solution? https://psbiztalk.codeplex.com/
