I deleted the experience fragment from Adobe Target . Now when i go to my AEM instance then I get option to Delete/Update the Experience Fragment in Target.
But when I try to do so I get an error that it cannot be Deleted/Updated. (Reason: "Caused by: java.lang.Exception: Unexpected response status code  for request" "Offer not found. Some other user might have deleted it.").
Please let me know how can I republish my XF to Target.
I suggest that you reach out to the AEM support group to see if there is a special way to do that however the first idea that came to my mind was to publish a slightly different new one like: "Hackathon-XF-V2" and that should do it.
If this satisfies your query please like, mark as helpful and mark as answer. Otherwise lets keep the conversation going. Hope you have a wonderful day.
Thanks for your suggestion. Creating a new XF and publishing to Target is a workaround but I was looking for some permanent solution so that in case in future if this kind of issue occurs then without creating any new XF we can republish the same/existing XF to Target.
Will connect to AEM support group and check if there is any such provision.
