Bug report

Describe the bug

Every time we try to import the configuration for our models we get an error toast, looking on the console we get this error:

XHRPOSThttp://localhost:1337/config-sync/import

And going to the network, we can see this.

Moving to the content manager, we get two behaviours:

1. The configuration settings were properly loaded.
2. The admin user lost all the permission and cannot see anything.

Steps to reproduce the behavior

1. Go to Content Manager.
2. Click on Config Syng > Tools.
3. Select all the files you want to import.
4. Import them.
5. See the toast error.
6. Go to Console.
7. Check the error.
8. Go to Network.
9. Check the error.

Expected behavior

It shouldn’t give an error at importing.
