Simulink code generation assertion - build fail

Hi,
I'm trying to build simulink C code and this is the problem:
"Error:Code generation assertion 'parameterMapFromConstantBlock.size() == 1' failed in 'B:\matlab\src\slcg_impl\SLCG\SLCGFixAxisLookupTableHelper.cpp:380'."
Has anyone encountered this kind of error and was able to solve it?
Thanks in advance!

The root cause of such an assertion is a bug and I believe our Technical Support team needs to investigate this further.
Please create a Technical Support case and if possible share a model which reproduces the error.
Here you can find the webpage to create a case:
