Hi, I'm documenting sd_bus_call and its async variant and I was wondering about the sd_bus_error output parameter that's passed to it. Is it specifically meant for use cases where we're doing a nested D-Bus method call from a service so we have an error object to send back from the initial D-Bus method call? I don't see immediately see the benefit of the sd_bus_error parameter in a D-Bus client since I can simply check the return value instead which seems to contain the same information looking at the implementation.
