Codegen is throwing the following error when doing code generation
"Internal error while creating code interface description file: codeInfo.mat. Aborting code generation.
Caused by:
  • Index exceeds the number of array elements. Index must not exceed 0. "
The error doesn't give any more information and hence cannot figure out what is the problem. Using ert based target file.

Hi Umar, thanks very much.
My colleague once encountered this problem. He deleted the folder where the builded code was stored and then build it again. After multiple repeated operations, the compilation was successfully completed.
So this may not be caused by issues with the Simulink model or array data.
I saw on this website that this bug has been resolved in Matalb 2022b. But it seems that we are still facing this problem.
I also saw someone encountering this problem in 2023a.
I don't know if this is a bug that Matlab hasn't fully resolved yet.
