Help in Restoring Assignment/Quiz Grades

[lmnicolas]

Can anyone help me, I have accidentally moved our existing section to a new course via SIS Import, when I noticed this, I moved back the original section to the original course.

However, upon doing this. the assignment/quiz grades of the student can no longer be found on the Grades menu.

I found out that I can manually restore the grades by editing the Assignment/Quiz and assign them to their respective sections but it will take a long time to check them each manually.

I also found this API Call (https://canvas.instructure.com/doc/api/all_resources.html#method.sis_imports_api.restore_states ), tried using cURL via the Windows 10 Command Terminal

"curl https://<canvas>/api/v1/accounts/<account_id>/sis_imports/<sis_import_id>/restore_states \ -H 'Authorization: Bearer <token>'"

I tried this command:"curl https://my.instructure.com/api/v1/accounts/1/sis_imports/12864/restore_states  -H "Authorization: Bearer my_key"

and this command 

curl https://my.instructure.com/api/v1/accounts/1/sis_imports/12864/restore_states  -H "Authorization: Bearer my_key" -F "undelete_only=true"

and I get this result in html format

"Page error

Any idea on how to solve this?

Thanks! any idea will be much appreciated !
