Unable to build standalone executable in rapid accelerator mode--Unable to find VarGroupIdx within the GlobalBlockOutput scope

Here's the specific error message:

Unable to build a standalone executable to simulate the model MODEL in rapid accelerator mode.

Caused by:

• Error: File: C:\Program Files\MATLAB\R2024b\rtw\c\tlc\lib\blkiolib.tlc Line: 2886 Column: 62 Unable to find VarGroupIdx within the GlobalBlockOutput scope

The offending section of code from blkiolib.tlc is:

%% Function: SLibGetBlockOutputIdentifierFromRecord ================================================
%% Abstract:
%%   From the .rtw file BlockOutputs Record get its base identifier in the
%%   block I/O structure to be accessed from within the accessSysIdx
%%
%function SLibGetBlockOutputIdentifierFromRecord(bo, accessSysIdx) void
%assign varGroup = ::CompiledModel.VarGroups.VarGroup[bo.VarGroupIdx[0]]
%return SLibCG_GetVarGroupElementPath(bo.VarGroupIdx, accessSysIdx, ...
System[varGroup.SysIdx].CrossNoArgFcnBound)
%endfunction

I'm not sure where to begin here. the MODEL.rtw file has GlobalBlockOutput sections, some of which have VarGroupIdx members and some of which do not. Is there a way to narrow down what's getting tripped over here?

You are receiving this error because Simulink Real-Time does not support accelerator mode or rapid accelerator mode simulation of models with blocks that represent hardware.
