I was facing same error when I was taking FFT for AM modulated signal.

Try typing spectrum analyzer and select spectrum analyzer one by one run and see which spectrum analyzer

is showing result and is suitable for your simulation.

From the figure, it seems to suggest that your data is complex but your block is set to compute one sided spectrum. I think you just need to configure the block to compute the two-sided spectrum.
