This is caused by a bug in Azure IoT extension for Azure CLI: Azure/azure-iot-cli-extension#95
Azure IoT extension for Azure CLI already fixed this error. You should no longer see this error.
I'm going to close this issue. Feel free to open new issues if you meet other problems when using Azure IoT Edge tasks.
