Can you try it in the latest development build? There were recent changes to the ai_tracker app for 1.17 that may (or may not) have fixed it.

If it still doesn't work, could you give more context about what you did (what command, what was around, anything you find relevant)?

Thanks!

Issue seems to be resolved with this build. No errors encountered.
