Declare Bad File Replcas fails silently

[dynamic-entropy]

Description

The Python client call to declare file replicas as bad fails silently, without giving any results to the user about success or failure.

The docs https://rucio.github.io/documentation/client_api/replicaclient#declare_bad_file_replicas for the command say that a list of dids for which the declaration failed is returned.
However, this does not seem to be the case.

Are there use cases where the silent failing is an intended behaviour?

Steps to reproduce

Use a random scope and name for a file with the command, with a valid RSE

>>> client.declare_bad_file_replicas([{'scope': 'cms', 'name': 'InvalidFileName', 'rse': 'T2_IT_Rome'}], reason='Lost on Disk')
{}
