Failed to receive data In eventcallback with large JSON payload #1764

Closed Heena2411 closed 2 years ago

Heena2411 commented 2 years ago

HI, I am using AWS SDK on my laptop having Ubuntu 20.04. I am trying to send costume JSON payload in desired state. While JSON data length is large, not able to get response in eventcallback. With smaller data it is working fine. Tried by changing NETWORK_BUFFER_SIZE, AWS_PAYLOAD_BUFF_SIZE. does this issue related to JSON payload length? Is there any limitation on length?

working payload: { "state": { "desired": { "a": 11111222223333333333111111111111111111111111111111190011111111111111111111111111111111111111111111111111111111111123, "b": 456, "c": 111, "d": 222, "e": 333, "f": 444, "g": 555, "h": 1 } }, "clientToken": "023798" }

Payload with no response: { "state": { "desired": { "a": 11111222223333311111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111133333111111111111111111111111111111190011111111111111111111111111111111111111111111111111111111111123, "b": 456, "c": 111, "d": 222, "e": 333, "f": 444, "g": 555, "h": 1 } }, "clientToken": "023798" }

Thank you for bringing this to our attention. Which eventcallback are you referring to specifically?

Heena2411 commented 2 years ago

Thanks for quick response. I am referring *eventCallback( MQTTContext_t pMqttContext, MQTTPacketInfo_t pPacketInfo, MQTTDeserializedInfo_t pDeserializedInfo ) and able to get payload print in updateDeltaHandler** with small payload.

Hi @Heena2411, Sorry for the late response - I did not see that you replied. I was wondering if you could provide me with some additional information. Is this for an mqtt demo - if so which one? What version of the code are you using?
