Dot indexing Error Running Script on Matlab Production Server

Hello,
I load a .mat file from a script running on Matlab Production Server. The file contains a struct.
Running on my desktop, I can access values in the structure like this:
histo_test = dataset_loaded(3).volfeats_EWM_histo.Values(2:10);
But on Matlab Production Server, that line of code produces this error:
'Dot indexing is not supported for variables of this type.'
I know the the structure loads correcly because the length of the structure is correct.
How can I access the parameters of a structure from a script running on Matlab Production Server?

After reading this question, I think this issue might be because you're loading a mat file with an output argument.
dataset_load = load('dataset_scaled_fixedBins.mat');
So, you can access the original structure data by accessing dataset_load.dataset_load.
dataset_loaded = dataset_load.dataset_load;
histo_test = dataset_loaded(3).volfeats_EWM_histo.Values(2:10);

Are there any data type difference in MATLAB desktop and MATLAB Production Server?
You can find data types by whos command
dataset_load = load('dataset_scaled_fixedBins.mat');
dataset_loaded = dataset_load.dataset;
dataset_length = size(dataset_loaded);
whos dataset_loaded
And you can find whos results in main.log of Production Server.
