Update 11/16/2022
The indexes are restored at UseGalaxy.org. Prior failed runs should now complete successfully.
Thanks to all who reported the issue for their patience!
Update: This was a bug. I opened a ticket for the correction here if interested: annotateMyIDs (several versions) is not really ignoring header line when option set · Issue #2319 · galaxyproject/tools-iuc · GitHub
Until that is completed, continue to remove header lines from any inputs to this tool, no matter which server or tool version you may be using.
