Error when receiving data with ESP32 Azure IOT Arduino

[oliverbru]

Hello,

I am using IOT Azure on Arduino IDE 1.8.10 with Wifi connection.
The device is able to send data via MQTT on Azure IOT Hub. No problem for that.
But when the device receives data, it reboots and I get this error :

23:48:07.225 -> Error: Time:Wed Oct 16 21:48:04 2019 File:C:\Users\...\AppData\Local\Arduino15\packages\esp32\hardware\esp32\1.0.4\libraries\AzureIoT\src\az_iot\umqtt\src\mqtt_client.c Func:recvCompleteCallback Line:665 failure in mqttmessage_create

23:48:07.319 -> Info: tlsio_openssl_close has been called when in neither TLSIO_STATE_OPEN nor TLSIO_STATE_ERROR.

I really do not understand what is happening.

Regards,
