The 11.x series of Xcode seems to have broken Xcode Server. Every bot that is configured to output an archive at the end of processing now fails.
The raw output log looks like the following:

** EXPORT FAILED **
This bot worked before the update to Xcode 11, and now does not. I've even created a new bot, on an entirely different server, and it has the same outcome.
An examination of the path '/Users/xcodeserver/Library/Caches/XCSBuilder' reveals there are no integrations assets at that level, but there are 'Bot' folders. I'm wondering if the export path is missing the 'Bots/{UUID}' component.
Anyone have any suggestions or possible fixes?
