``` local function _receive_status(sock) local line, err = sock:receive("*l") if not line then return nil, nil, nil, err end local version = tonumber(str_sub(line, 6, 8)) -- line is a boolean? ``` The error message is indeed very strange. According to the [documentation of the `tcpsock:receive`](https://github.com/openresty/lua-nginx-module/tree/v0.10.21#tcpsockreceive) function, the returned data should be a string type, but the error here says that it is a boolean type variable. Can you help capture a network packet from apisix to consul using tcpdump? This way we can see what kind of tcp payload triggered the above error. -- This is an automated message from the Apache Git Service.
