provenance information is returned when a service is called without query arguments, if DEBUG=False
At the moment, the services return an internal error, when called without arguments and DEBUG=True.
Therefore, the provenance information cannot be gathered from the services without addressing them with correct arguments.
The toardb_fastapi REST API gets its information on startup time querying the services without arguments.
This can now only be done, when the service is deployed in DEBUG mode.
Workaround: If the above solution is not feasible, maybe an additional endpoint /provenance could be added to the services.
