As the error message says the "receiver expecting signal type real but is being drive by signal type complex" - you could insert a Complex to Real-Imag and set the Output parameter to "Real" on the block dialog, so that the block outputs only the real component of the signal. Of course you need to figure out if this is the right thing to do for your model.
