Description of the bug

When running a U-Norm workflow and trying to explore the workflow topology, I'm getting the following error when trying to get the raw DataSources back: TypeError: <class 'ansys.dpf.core.data_sources.DataSources'> is not currently supported by the Any class..

Steps To Reproduce

Here is how to reproduce:

from ansys.dpf import core as dpf
from ansys.dpf.core import operators

workflow = dpf.Workflow()

op_displacement = operators.result.displacement(
    data_sources=dpf.DataSources("./path/to/datasources.rst")
)

workflow.add_operator(op_displacement)

topology = workflow.get_topology()

for data_connection in topology.data_connections:
  print(data_connection.source_data) # The access to the source_data raises
