Ok, thanks for trying that. I ran a few tests, at different servers and using different versions of the tool – all fail in a similar way. I’m not sure why so will reply again once known.
To use the tool now, first run the tool Remove beginning of a file to remove the first line (header), then run the tool annotateMyIds. That worked in my tests, across servers and tool versions.
Appreciate the follow up – this was unexpected!
