Cannot add content to iTunes U using Woolamloo Automator Action

Question

We cannot use the Woolamloo Automator action to add any content to our iTunes U site recently. Ex: We created a workflow using “Get iTunes U XML” , “Find Sections in iTunes U XML” and “Add divisions into iTunes U” actions, the returned result was the section handle to which the division was expected to be added and the the log said “ Get iTunes U XML completed, Find Sections in iTunes U XML completed, Add Divisions into iTunes U completed, Workflow completed”, however, no division was added to the section actually. It’s the same with other adding content actions. But we had no problem with deleting actions.
Meanwhile, we cannot access the iTunesU webservices, either. When we try “curl https://deimos.apple.com/WebObjects/Core.woa/API/ShowTree/nd.edu.roothandle?​credentials=(administrator credential)&identity=(identity)&time=(time)&signature=(signature)&x=true”, the result is : “Forbidden. You don’t have permission to access this document on this server”. Any suggestions would be highly appreciated.

Answer 1

Yes, we still have this problem.
We believe the shared secret and credentials are correct because we can get the site XML via Woolamaloo Automator action.
We also attached the debug suffix in the script and the result was "Because the received signature and time were valid, the received identity and credentials were accepted by iTunes U." And we can use the same signature to log in to our iTunes U site. But when performing the HTTP GET request, we got the "request is forbidden" error.
Thanks for your help, we do appreciate.
