KeyError issue - unable to find root cause

[buran]

So I assume you download it as csv and then pass the path/filename as argument
read_file function will not work in this case because it expects json, not csv file
so best is to use csv module

import requests
import sys,os
import datetime
import json,time
from functions import read_file,getdate
from functions import getcurrentdate,constructJson_Request
from functions import postURL,send_mail
import csv
 
currentdate = getcurrentdate()
 
config_filepath = os.getcwd()+"/configuration.json"
configuration = read_file(config_filepath,"configuration")

with open(sys.argv[1]) as workorder_file:
    rdr = csv.DictReader(workorder_file)
    for req in rdr:
        send_to = req['emailid']
        subject = "Request ID:" + req['workorderid'] + " - Reminder 1"
        text = "Request ID:" + req['workorderid'] + " - Reminder 1"
        resp = send_mail(configuration, send_to, subject, text)
        print("Mail Sent" + resp)
