Error: Unable to invoke service on Connection Services Hub: No Things are connected to handle request for service <serviceName>
All of the services that involve the Azure Storage depend on the correct configuration and availability of the AzureBlobStorageTemplate Thing. If the ThingWorx Platform cannot communicate with the Azure IoT Hub Connector, the following error appears when you attempt to execute any of these services:
Unable to Invoke Service [serviceName] on ConnectionServicesHub :
No Things are connected to handle request for service [serviceName]
For example, if you attempt to transfer a file to the Azure Blob Storage using the Copy service and this error appears, it is possible that the configuration of the AzureBlobStorageTemplate Thing in the AzureIotHub Thing is not correct.
Solution
From ThingWorx Composer, check the configuration of the AzureIotHub Thing to be sure that the following properties are set correctly for the AzureBlobStorageTemplate Thing:
• The accountName of the AzureBlobStorageTemplate Thing
• The connection string of the AzureBlobStorageTemplate Thing
If you change the configuration, you MUST restart the Connector.
