no matching function for call to 'SocketIoClient::on(const char [6], void (&)(uint8_t*, size_t))'

Hi, I'm using arduinoi IDE for windows and when i compile your basicExample get this error: C:\Program Files (x86)\Arduino\libraries\socket.io-client\examples\BasicExample\BasicExample.ino: In function 'void setup()': BasicExample:39: error: no matching function for call to 'SocketIoClient::on(const char [6], void (&)(uint8_t*, size_t))' webSocket.on("event", event); ^ C:\Program Files (x86)\Arduino\libraries\socket.io-client\examples\BasicExample\BasicExample.ino:39:32: note: candidate is: In file included from C:\Program Files (x86)\Arduino\libraries\socket.io-client\examples\BasicExample\BasicExample.ino:7:0: C:\Program Files (x86)\Arduino\libraries\socket.io-client/SocketIoClient.h:34:7: note: void SocketIoClient::on(const char*, std::function<void(const char*, unsigned int)>) void on(const char* event, std::function<void (const char * payload, size_t length)> func); ^ C:\Program Files (x86)\Arduino\libraries\socket.io-client/SocketIoClient.h:34:7: note: no known conversion for argument 2 from 'void(uint8_t*, size_t) {aka void(unsigned char*, unsigned int)}' to 'std::function<void(const char*, unsigned int)>' exit status 1 no matching function for call to 'SocketIoClient::on(const char [6], void (&)(uint8_t*, size_t))' what's the problem?

Hey! change the function event to

void event(const char * payload, size_t length) {
     USE_SERIAL.printf("got message: %s\n", payload);
}

the type of the first parameter is wrong in the example
