MATLAB local variables in the code may not have been initialized

Hello ,

I am getting following MISRA error for R2018b Autosar Code:

Warning 644: Variable 'rtb_Rdr_IN_ConfigDataRdr_RdrRat' (line 863) may not have been initialized [MISRA 2012 Rule 9.1, mandatory]

Above line in the model is NV sender receiver port also same error is occuring for all the outputs which are sender receiver port.
