For an inverse design problem, SU2 fails to calculate INVERSE_DESIGN_PRESSURE for adjoint calculation. SU2_CFD runs without any errors, while the solver enters the adjoint calculation design phase using the shape_optimization.py script it exhibits the following key error:

File "C:\SU2\bin\SU2\eval\functions.py", line 118, in function func_out = state['FUNCTIONS'][func_name] KeyError: 'INVERSE_DESIGN_PRESSURE'

I have attached the files used for the simulation. Any help is appreciated.

Thanks.
