ArcGIS Python API append new record

Question

I am trying to insert a python dict record to the hosted online service. I am getting the following error:

Traceback (most recent call last): File "", line 1, in File "C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\lib\site-packages\arcgis\features\layer.py", line 2824, in edit_features if isinstance(adds[0], dict): KeyError: 0

My dict is:

{

}

MY code is :

import arcpy
from arcgis.features import FeatureLayer
lyr_url = 'https://services6.arcgis.com/A1NU60yx0I8XSDFS/arcgis/rest/services/ValvesTest/FeatureServer/0'

layer = FeatureLayer(lyr_url)
feature_count = layer.query(return_count_only=True)
print("Feature Count: ", feature_count)
layer.manager.truncate()
feature_count = layer.query(return_count_only=True)
print("Now Feature Count: ", feature_count)

fc = "E:\\ABC\\gaspopups.gdb\\DistributionGasValve"

feature = None
cursor = arcpy.da.SearchCursor(fc, ["*"])
row = next(cursor)
feature = {field: value for field, value in zip(cursor.fields, row)}
layer.edit_features(adds=feature )

How to go about it?
