Issues using XYPlots on Pylfluent

[GauthamVarma91]

Hello, So i am running a simple conduction problem and wanted to plot the temperature profile in the direction of conduction i have run the following code to execute the same.

session.results.surfaces.line_surface.create()
session.results.surfaces.line_surface["line-1"] ={'name': 'line-1', 'p0':[0,0,0],'p1':[0,0,-0.2]}
plots_session = Plots(session)
xy_plot1 = plots_session.XYPlots["xy-plot"]
xy_plot1.surfaces_list = ["line-1"] 
xy_plot1.y_axis_function = "temperature"
xy_plot1.x_axis_function = "direction-vector"
xy_plot1.direction_vector.set_state([0, 0, 1])
 
xy_plot1.plot("xy-plot")

Howeverr, I am getting the following error .
RuntimeError: Plot surface is not valid.
Could someone help me with this?
