hammer content-export ["Path '' is not an allowed export path"]}

Satellite 6.10
Redhat 7.9

Running the following

hammer content-export complete library --organization=my_org

Results in:

Response body: {"path":["Path '/export_folder_path/Export-Library/13.0//2022-06-02T13-35-51-04-00' is not an allowed export path"]}

I set the destination correctly:

hammer settings set --name pulp_export_destination --value /export_folder_path

one thing that is obvious is that there is a double slash "//" in the path in the error above. So why the above error?

To clarify, the /export_folder_path folder is owned by foreman:foreman, octal permissions are 755 recursively.
