Sending Writable Property from IOTC to ESP8266 not working properly.

[avokhour]

Hello there,

I am using a esp8266 for my iot project and I came across an error which I did not find any solution for it.
I am sending property from Device to IoT central and it is working perfectly.
While sending property from Cloud to Device then the problem starts.
While sending a property with a value of 0 then the esp8266 is accepting it, but when the value changes then it says you have a NULL value.

The below are seen on the serial monitor when I send values different then 0.

**X - Error at ../common/iotc_json.h:119
(getNumberByName) object == NULL!

• • [SettingsUpdated] event was received. Payload => {"Property1":1,"property3":1,"property4":1,"property5":1,"$version":19}
• • Command name was => property5
• • Setting name was => property5

X - Error at ../common/iotc_json.h:119
(getNumberByName) object == NULL!**

The below are seen on the serial monitor when I send values 0.

**- - Command name was => Property1

• • Setting name was => Property1
• • [SettingsUpdated] event was received. Payload => {"Property1":{"requested":{"value":0}},"property3":{"requested":{"value":0}},"property4":{"requested":{"value":0}},"property5":{"requested":{"value":0}},"$version":20}
• • Command name was => property3
• • Setting name was => property3
• • [SettingsUpdated] event was received. Payload => {"Property1":{"requested":{"value":0}},"property3":{"requested":{"value":0}},"property4":{"requested":{"value":0}},"property5":{"requested":{"value":0}},"$version":20}
• • Command name was => property4
• • Setting name was => property4
• • [SettingsUpdated] event was received. Payload => {"Property1":{"requested":{"value":0}},"property3":{"requested":{"value":0}},"property4":{"requested":{"value":0}},"property5":{"requested":{"value":0}},"$version":20}
• • Command name was => property5
• • Setting name was => property5**

How can I fix this problem?
If I have to define a property in the device in order to save and store the value, how can I do it?
