how to use await() in coroutine?

[jinguo-yin]

I use coroutine.create(func) create one coroutine, using :await() in func, when JS promise is resolved,but in coroutine' await() not return;

my code is: function LedFlashFunc() local isOn = true while true do wait(1000)
print('LedFlashFunc') if isOn then local result = LedOn():await() else LedOff():await() end isOn = not isOn end end

local co = coroutine.create(func) local succeed, result = coroutine.resume(co) if not succeed then print('LUA Error: ' .. tostring(result)) end
