Upload failure
The upload fails because of a missing source.
Scenario
The New upload view displays a Source input field with a drop-down menu.
Issue
The Source field is marked as mandatory.
The drop-down menu is empty. Therefore, it is not possible to make any valid selection.
Since a mandatory field is left empty, the upload fails.
Cause
Either no user groups are configured in the Intelligence Center;
Or the Intelligence Center has one or more configured user groups, but the current user is not part of any existing group.
Solution
The current user needs to be part of an Intelligence Center user group to be able to upload files manually.
If there are no configured user groups:
Create a group.
Add the current user to it.
If the current user is not part of any existing group:
Add the current user to an existing group.
After you are done, proceed to manually upload the files again.
