How can we get a record by id?

Helpdesk.Support.get! Helpdesk.Support.Ticket, ticket.id

Helpdesk.Api.read_support_ticket ticket.id

{:error,
 %Ash.Error.Invalid{
   errors: [
     %Ash.Error.Invalid.MultipleResults{
       count: 2,
       at_least?: true,
       changeset: nil,
       query: nil,
       error_context: [],
       vars: [],
       path: [],
       stacktrace: #Stacktrace<>,
       class: :invalid
     }
   ],
   stacktraces?: true,
   changeset: nil,
   query: nil,
   error_context: [],
   vars: [],
   path: [],
   stacktrace: #Stacktrace<>,
   class: :invalid
 }}
