I cannot set 2 ffts with different input width and output width.

I have shared my project.

if I commit the code below, it will be compilated ok.

fft3 ifft1_inst(
.clk(clk),
.reset_n(reset_n),
.sink_valid(fft1_source_valid_s),
.sink_ready(),
.sink_error(2'b00),
.sink_sop(fft1_source_sop_s),
.sink_eop(fft1_source_eop_s),
.sink_real(real_fft1_fre[12-1:0]),
.sink_imag(imag_fft1_fre[12-1:0]),
.fftpts_in(5'd16),
.inverse(1'b1),
.source_valid(ifft1_source_valid),
.source_ready(1'b1),
.source_error(),
.source_sop(ifft1_source_sop),
.source_eop(ifft1_source_eop),
.source_real(real_ifft1_out),
.source_imag(imag_ifft1_out),
.fftpts_out()
);
