Sorry for late reply, it has been fixed in this pr #11

[jk-tonycui]

I tried the fix, but it seems still not working. I tried to add some log into echoHandler:on_response method in the echo.lua, but log didn't show up either. It seems the echo.lua didn't load successfully.

I saw some error log in log of envoy, please help to check the logic.

@jk-tonycui it works in my test, could you show me your response headers?
