File Transfer Event error when repository-thing=name Thing does not exist or implements wrong Thing Shape
When a file is uploaded to an Azure Storage Account Blob Container, the Azure IoT Hub Connector fires a FileTransfer event on the ThingWorx Platform. This event is fired on the cx-server.protocol.file-upload-events.repository-thing-name Thing specified in the configuration file of the Connector. If there is not a AzureStorageContainerFileRepository Thing with a name that matches the repository-thing-name, an error similar to the following error is logged in the ThingWorx Platform Error Log:

The Connector loads and caches all configuration settings during startup. If you make a change to the configuration, you MUST restart the Connector so that the change takes effect.
