Provision device example not compiling
Hi
For some reason https://github.com/thingsboard/thingsboard-arduino-sdk/blob/master/examples/0008-esp8266_provision_device/0008-esp8266_provision_device.ino is not compiling on Windows Arduino IDE 1.8.19 for FireBeetle ESP32.

@OekoSolveMG could you take a look? Or @ashvayka @forGGe @ikulikov @ferchinas?
Trying my luck here, as there's not too much interest in my issue :) Has anyone else gotten this to work? @JfloresIoTF @imbeacon @AdrienAdB @farmerkz @NgocThinhNTP18 @camiloconcha @kmilokeepex
@gittimotap The fix for the example code needs to be fixed in two places, but luckily both fixes are simple:
// ...
// FIX #1
//
// We're dealing with const data
//
//JsonObject credentials_value = data["credentialsValue"].as<JsonObject>();
JsonObjectConst credentials_value = data["credentialsValue"].as<JsonObjectConst>();
// ...
// FIX #2
//
// Provision_Callback is a class that takes the callback as a constructor parameter
//
//const Provision_Callback provisionCallback = processProvisionResponse;
const Provision_Callback provisionCallback(processProvisionResponse);
// ...
EDIT: While this allows it to compile, I've yet to get the actual provisioning to work, but I'll try to update here whether I get it working or not.
@imbeacon I think this issue can be closed, all examples now compile successfully and work with their corresponding boards.
