Error while reading data from host

Hello, I have a strip of leds WS2811 connected to the raspberry pi 3b +. In the first case I connect two cables to the power supply and then connect the other three cables to the gnd pin, the clk pin and the data pin. Active spi in the file config.txt and I put the core_freq = 250. I do the installation step by step correctly and in no time it gives error, finally with hypercon I export the file hypercon.config.json and I put it in /etc/hyperion.The thing is that it starts correctly (does not give error), but it does not makes the rainbow effect. If I try to change the color sudece an error:
osmc@osmc:~$ hyperion-remote --priority 50 --color red --duration 5000
