RuntimeError: Error while requesting data from server.(('type', 'pathlines-field'), ('field', 'velocity-magnitude'))

📝 Steps to reproduce

Run the following in a python interpreter:

import ansys.fluent.core as pyfluent
from ansys.fluent.core import examples

from ansys.fluent.visualization import set_config
from ansys.fluent.visualization.matplotlib import Plots
from ansys.fluent.visualization.pyvista import Graphics

set_config(blocking=True, set_view_on_display="isometric")

import_case = examples.download_file(
filename="exhaust_system.cas.h5", directory="pyfluent/exhaust_system"
)
import_data = examples.download_file(
filename="exhaust_system.dat.h5", directory="pyfluent/exhaust_system"
)
solver_session = pyfluent.launch_fluent(
precision="double", processor_count=2, start_transcript=False, mode="solver"
)
solver_session.tui.file.read_case(import_case)
solver_session.tui.file.read_data(import_data)
graphics = Graphics(session=solver_session)
pathlines = graphics.Pathlines["pathlines"]
pathlines.field = "velocity-magnitude"
pathlines.surfaces_list = ["inlet", "inlet1", "inlet2"]
