I am doing some test using export and import groups data. I was able to export a group content and download it as test_20221005_112827.epk and when I am trying to do the exercise to import the epk file to other portal, fist I use add new item option in order to get item id for import and I got this error.
I also tried to do this from Server admin api and I got the same error.
and from this esri's web page says i can add this item
I tried to add this item in 3 separates 10.9.1 portals and in all of them I got the same error.
What can It be?
