Please run this segment of debugging code and tell us the result.

OutputData = data1.OutputData;
if isempty(OutputData)
    fprintf('Stored OutputData is empty\n');
    output_size = 0;
elseif iscell(OutputData)
    fprintf('OutputData is cell\n');
    output_size = size(OutputData{1});
else
    fprintf('OutputData is numeric\n');
    output_size = size(OutputData);
end
disp(output_size)
