FeatureLayerCollection insert_layer() only works if there are no tables present in the Feature Service

[Clubdebambos]

Describe the bug
If you have none, one, or multiple feature layers present in a feature service with no table(s) then the insert_layer() method works just fine (although the name parameter is not honored). However, if you have a single table (or more) in your feature service the insert_layer() method will fail.

To Reproduce
Have a feature service with a table(s)

agol = GIS("home")

item = agol.content.get("FS_ITEM_ID")

shp_path = r"C:\Path\to\Zipped_Shapefiles\Shapefile.zip"

flc = FeatureLayerCollection.fromitem(
    item = item
)

#use the flc object insert_layer() method to create a feature layer 
status = flc.manager.insert_layer(
    data_path=shp_path,
    name="County Boundaries Layer" # does not honour
)

print(status)

error:

Expected behavior
The layer should be inserted whether tables exist or not in the Feature Service
