OfflineContentManager export_items fails for "Table (hosted)" feature service

Describe the bug
When using OfflineContentManager's export_items method, it fails unexpectedly for a "Table (hosted)" feature service. (See error message below.)

To Reproduce

Create a Table (hosted) either by uploading a simple CSV file or via Content --> New item.
Attempting to make an offline backup of the item using export_items produces the following error:

C:\Users\knoop\AppData\Local\ESRI\conda\envs\work\Lib\site-packages\arcgis\apps\itemgraph\_migration.py:149: RuntimeWarning: Failed to export item b570d7c8577042d891d4eb09d348f331 due to error: <Table url:"https://services1.arcgis.com/4ezfu5dIwH83BUNL/arcgis/rest/services/OCM_export_items_csv/FeatureServer/0"> is not JSON serializable. Deleting folder and skipping...
  warnings.warn(

The above error message looks to have truncated prematurely as well.

Expected behavior
I expect export_items to be able to successfully export a "Table (hosted)" feature service.

Platform (please complete the following information):
Python API version 2.4.2

I cannot reproduce this issue with ArcGIS Online, please provide sample data and reproducible code.

from arcgis.gis import GIS, Item, ContentManager
gis = GIS(profile='your_online_profile', verify_cert=False, trust_env=True)
item: Item = gis.content.get('abc1234') # hosted table
cm: ContentManager = gis.content
result = cm.offline.export_items(items=[item], output_folder=r"c:\temp", package_name="tableexport")

@achapkowski

@achapkowski The error occurs with a Table (hosted) on ArcGIS Online.

The example Table (hosted) in the snippet below is shared publicly, but owned by a different user than the admin user running the code.

import arcgis
from arcgis import GIS
import os
import pandas

# Connect to ArcGIS Online organization as an admin user
gis = GIS(profile="xxxxxxxx")  

# Items to backup (publicly shared)
items = [
    gis.content.get('b570d7c8577042d891d4eb09d348f331')
]
display(pandas.DataFrame(items, columns=["id","type","typeKeywords","title"]))

# Export offline backup package
package_path = gis.content.offline.export_items(
    items = items,
    output_folder = os.getcwd(),
    package_name = "ocm_tile_layer_hosted",
)
print(package_path)

@knoopum thanks for the code snippet, I'll test it out
