I've been getting the following issue on using Blynk

Neopixel ‘strandtest’ working fine offline. When I am trying to connect the same to Wifi using ESP8266 with Blynk, I’m getting the following error while compiling-

Arduino: 1.6.7 (Windows 10), Board: “NodeMCU 1.0 (ESP-12E Module), 160 MHz, 115200, 4M (3M SPIFFS)”

Build options changed, rebuilding all

// Parameter 2 = Arduino pin number (most are valid)
// Parameter 3 = pixel type flags, add together as needed:
// NEO_KHZ800 800 KHz bitstream (most NeoPixel products w/WS2812 LEDs)
// NEO_KHZ400 400 KHz (classic ‘v1’ (not v2) FLORA pixels, WS2811 drivers)
