Question

我是LUA / ESP8266的初学者，我试图找出此错误的来源：

PANIC: unprotected error in call to Lua API (bad argument #2 to 'set' (index out of range))

这是串行监视器中的整个消息：

我将此代码（https://github.com/Christoph-D/esp8266-wakelight）上传到ESP8266，并使用所有必需的模块构建了正确的NodeMCU固件。

串行输出在几秒钟内都正常，然后出现此错误，并且开始重复重启。

我将从哪里开始寻找问题？

非常感谢！

编辑：lua文件中只有很少的地方写有关于“ set”的任何内容：

local function update_buffer(buffer, c)
  if not c.r_frac then c.r_frac = 0 end
  if not c.g_frac then c.g_frac = 0 end
  if not c.b_frac then c.b_frac = 0 end
  local r2 = c.r_frac >= 0 and c.r + 1 or c.r - 1
  local g2 = c.g_frac >= 0 and c.g + 1 or c.g - 1
  local b2 = c.b_frac >= 0 and c.b + 1 or c.b - 1
  local r3, g3, b3
  local set = buffer.set
  for i = 1, NUM_LEDS do
    if i > c.r_frac then r3 = c.r else r3 = r2 end
    if i > c.g_frac then g3 = c.g else g3 = g2 end
    if i > c.b_frac then b3 = c.b else b3 = b2 end
    set(buffer, i - 1, g3, r3, b3)
  end
end

有什么问题吗？

Python / Lua（（参数＃2的'set'错误（索引超出范围）））
