Using direct lookup table as input to a matlab function block in simulink => error in "Check Block Compatibility" of "HDL Workflow Advisor"

Hello everyone,

In my Simulink model I have a matlab function block, with the following code:

function device_exist = look_4_device_addr(device_list, device_addr)
%#codegen
device_exist=logical(0);
for indice = 1:length(device_list)
    if device_addr==device_list(indice)
        device_exist=logical(1);
        break;
    end;
end;

and in my simulink model I have the following blocks:

as you can see I'm giving the matlab function block a "direct lookup table" as input "device_list", so the function can search for the device_addr inside this direct lookup table.

This works fine in simulation, but in the hdl workflow advisor i get the following error in the "check Block Compatibility" step:

Internal Error: Evaluation of validate function on class hd defaults.DirectLookupTable failed with the error message: MATLAB:cellRefFromNonCell: Brace indexing is not supported for variables of this type.

Can you please help me figure out the problem. Am I not supposed using direct lookup tables as arrays to a matlab function simulink block? also it's a bit strange because I'm not using any braces anywhere and why is this supposed problem not reported in simulation?

This is a capture of table data parameter:

Thank you for your help, very much appreciated.
