Problems With GetFriendsCount

[sergeibellagamba]

Hi, I'm a complete amateur to this and I have tried following your instructions but I'm running in to this error in the Arduino IDE when compiling the code:

Arduino: 1.8.4 (Windows 10), Board: "NodeMCU 0.9 (ESP-12 Module), 80 MHz, 4M (1M SPIFFS), v2 Prebuilt (MSS=536), Disabled, None, 115200"

C:\Users\serge\Documents\Arduino\GetFriendsCount\GetFriendsCount.ino: In function 'void setup()':

GetFriendsCount:70: error: no matching function for call to 'FacebookApi::FacebookApi(WiFiClientSecure&, String&)'

api = new FacebookApi(client, FACEBOOK_ACCESS_TOKEN);

                                                  ^

This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences.

Any help would be much appreciated, thanks.

Thanks for the report, this is a bug for sure.

As a temporary workaround can you please change this line

api = new FacebookApi(client, FACEBOOK_ACCESS_TOKEN);

to

api = new FacebookApi(client, FACEBOOK_ACCESS_TOKEN, "", "");

and see if that works

HI Brian,

Thanks for the very prompt reply.

I have amended the code and it now seems to work. I am getting the following response in the serial monitor:

Failed to open config file JSON respnse was not as expected Facebook Friends: 89

And then after five mins I got:

JSON respnse was not as expected JSON respnse was not as expected Error getting friends count

This then repeated after another five mins.

I will unplug the ESP8266 and try again later to see what is returned.
