getting 998 when reading data in timer interrupt #1

Hi, I've connected SHT sensor to the NodeMCU V 0.9. When reading sensor data in a loop or with a delay mechanism, it works fine. But I'm trying to get the sensor data in a Timer interrupt using the Ticker library on ESP core. it doesn't matter how long this interval is, it just doesn't work. I have also tried using SHT10 sensor with the proper library and the same happens there too. Any idea what the problem might be?

Why reading sensor data in the interrupt? In the ISR cycle you should spend the less time possible in it.
