error: with_dict expects a dict

I have this in my group_vars:

hotfixes-6_2_0:
XS62ESP1003:
dl_file: XS62ESP1003.zip
dl_path: “http://downloadns.citrix.com.edgesuite.net/akdlm/9031/
XS62ESP1005:
dl_file: XS62E005.zip
dl_path: “http://downloadns.citrix.com.edgesuite.net/akdlm/8197/
XS62ESP1009:
dl_file: XS62E009.zip
dl_path: “http://downloadns.citrix.com.edgesuite.net/akdlm/8452/

My play says:

Can you rename hotfixes to avoid the dash?(-) and try again?
