Got Fatal exception 28(LoadProhibitedCause) when using ThingerSmartConfig

Client Libraries

Hi guys,
I’m building a gas sensor on NodeMCU v3 board and I’d like to use deep sleep feature so that to run on low power profile. Having read many guides of how to build such a system with thinger IoT I came up with a code that (from my perspective) should run well, but it doesn’t and I receive Fatal exception 28(LoadProhibitedCause) error.

One more note: I had to set #define DISABLE_TLS because otherwise it would fail with [_SOCKET] Error while connecting! error.

My set-up:
thinger-io 1.6.2
NodeMCU v3 LoLin 1.0

Arduino IDE 1.8.8
esp8266 2.5.2
thinger.io 2.13.0

ESP code
#define THINGER_SERVER “XXX.XXX.XXX.XXX”
#define DEBUG
#define DISABLE_TLS

#include <ESP8266WiFi.h>
#include <ThingerESP8266.h>
#include <ThingerSmartConfig.h>

#define MQ2pin A0

#define USERNAME "<<USERNAME>>"
#define DEVICE_ID "NODEMCU1"
#define DEVICE_CREDENTIAL "<<CRED>>"

float sensorValue; 
ThingerSmartConfig thing(USERNAME, DEVICE_ID, DEVICE_CREDENTIAL, false);

void setup() {
Serial.begin(9600);
Serial.println("Gas sensor warming up!");
delay(20000); 

thing["air_quality"] >> outputValue(getSensorValue());
}

void loop() {
pson data;
data["air_quality"] = getSensorValue();
if (int(getSensorValue()) >= 300) {
thing.call_endpoint("telegramAlert", data);
}

thing.handle();
ESP.deepSleep(20e6);
}

float getSensorValue() {
sensorValue = analogRead(MQ2pin); 
return sensorValue;
}
