Error while exporting

While exporting data from my metabase server, after some time i get this error

   at System.Linq.ThrowHelper.ThrowArgumentNullException(ExceptionArgument argument)
   at System.Linq.Enumerable.Select[TSource,TResult](IEnumerable`1 source, Func`2 selector)
   at metabase_exporter.MetabaseApiExport.GetMappedDashboards(MetabaseApi api, IReadOnlyDictionary`2 cardMapping, IReadOnlyCollection`1 exportedCollections) in /sln/metabase-exporter/MetabaseApiExport.cs:line 48

   at metabase_exporter.Program.<Main>(String[] args)
qemu: uncaught target signal 6 (Aborted) - core dumped

Maybe there is some issue with data in my metabase, not really sure. Any help is appriciated.
