Hello,
I changed my code from mongoose os to use the C SDK. I can send messages but the example for esp32 (https://github.com/Azure/azure-sdk-for-c-arduino/blob/main/examples/Azure_IoT_Hub_ESP32/Azure_IoT_Hub_ESP32.ino) output message is not clear to me. I have an azure function to get the message and put it into azure table storage but it gives me the following error:

[Error] Executed 'Functions.EventHubTriggerJS' (Failed, Id=f2317aa0-5742-4857-a318-19369ae15400, Duration=1ms)
Binding parameters to complex objects (such as 'Object') uses Json.NET serialization. 
1. Bind the parameter type as 'string' instead of 'Object' to get the raw values and avoid JSON deserialization, or
2. Change the queue payload to be valid json. The JSON parser failed: Unexpected character encountered while parsing value: E. Path 'deviceID', line 1, position 14.

The code for my azure function is in nodejs and I use table API to store it in table (I know I can use binding too but want to use the API):

const entity = {
            PartitionKey: "ESP32,
            RowKey: new Date().getTime().toString(),
            distance: iotHubMessage.x,
        };
        await client.createEntity(entity)

I must say that it was working before (with previous sdks). The code was:

char buff[128];
float x = (float)random(0, 100);
sniprintf(buff, 256, messageData, "123", x);
if (Esp32MQTTClient_SendEvent(buff)):
....

I also wanted to see how can I debug azure functions which are triggered by iotHub events. It was working few days ago when I was running the debugger and send messages to iotHub, but suddenly stopped working. Now I cannot use vscode debugger and check the messages and debug. It makes everything more difficult.
