Is there any limitation to define multi instants of FastLED object?

Is there any limitation to define multi instants of FastLED object? Actually I’ve tried to use multi strip on ESP pins ( 0,2,4,5,12,13,14,15) and define 8 instant of FastLED.addLeds<LED_TYPE, PINx, COLOR_ORDER>(leds[x], 60); but I could only have 7 instant and compiler throw error for the 8th instance, no matter what pin number is, any hint really appreciated

What error did the compiler throw?
