Error when migrating HDRIBackdrop from UE5 to UEFN

I get the error in the image below when migrating HDRIBackdrop from UE5 to UEFN.
I don’t know how to solve this problem, so please help me.

Error contents
Some selected assets do not have a content route corresponding to the destination.
/HDRIBackdrop

Do you want to migrate all selected assets to the folder containing the merged references? If you do not migrate to a folder, the assets in the above root will not be migrated.

@k-hide420 Thank you for your report! We would like to look into this further, would you be able to submit a bug report using the form available here? Fortnite Creative

Did you migrate to the “content” folder of the project? If not, you ll get this issue iirc

Thank you for your comment.
The same phenomenon occurs when I put it in CONTENTS.

Thank you for your comment.
I have not reported it yet and will do so in the future.

Ok, then try to export from your other project, then import into UEFN, instead of migrating. That usually works for me.
