Cannot use exported configuration

[MarcSkovMadsen]

I would expect to be able to serve

import pandas as pd
import panel as pn

from panel_gwalker import GraphicWalker

pn.extension(sizing_mode="stretch_width")

LOGO = "https://kanaries.net/_next/static/media/kanaries-logo.0a9eb041.png"

df = pd.read_csv(
    "https://datasets.holoviz.org/windturbines/v1/windturbines.csv.gz", nrows=10000
)

walker = GraphicWalker(df, sizing_mode="stretch_both", styles={"border": "1px solid yellow"})

pn.template.FastListTemplate(
    logo=LOGO,
    title="Panel Graphic Walker",
    main=[walker],
    main_layout=None,
).servable()

Configure the walker:

Export the configuration

and use it

walker = GraphicWalker(df, config=config, sizing_mode="stretch_both", styles={"border": "1px solid yellow"})

pn.template.FastListTemplate(

    main_layout=None,
).servable()

But it does not seem to work as I don't get the configuration exported:
