google api (sheets) Request had insufficient authentication scopes

Question

i want to read an write data from a sheet, reading works fine but writing doesn't. i use all the scopes mentioned in the documentation: https://developers.google.com/sheets/api/reference/rest/v4/spreadsheets.values/append

data_writer(1,1,1)

code:

from __future__ import print_function
from apiclient.discovery import build
from httplib2 import Http
from oauth2client import file, client, tools
# Setup the Sheets API
SCOPES = 'https://www.googleapis.com/auth/spreadsheets'+"https://www.googleapis.com/auth/drive.file"+"https://www.googleapis.com/auth/drive"
store = file.Storage('credentials.json')
creds = store.get()
if not creds or creds.invalid:
    flow = client.flow_from_clientsecrets('client_secret.json', SCOPES)
    creds = tools.run_flow(flow, store)
service = apiclient.discovery.build('sheets', 'v4', http=creds.authorize(Http()))

# Call the Sheets API
SPREADSHEET_ID = '1JwVOqtUCWBMm_O6esIb-9J4TgqAmMIdYm9sf5y-A7EM'
RANGE_NAME = 'Jokes!A:C'
# How the input data should be interpreted.
value_input_option = 'USER_ENTERED'  
# How the input data should be inserted.
insert_data_option = 'INSERT_ROWS' 

def data_reader():
    #reading data
    read = service.spreadsheets().values().get(spreadsheetId=SPREADSHEET_ID,range=RANGE_NAME).execute()
    #reading values
    values = read.get('values', [])
    if not values:
        print('No data found.')
    else:

        for row in values:
            print(row[2])
            continue
def data_writer(score,num_comments,mystring):
    value_range_body = {
        "score":score,
        "num_comments":num_comments,
        "joke":mystring
    }
    request = service.spreadsheets().values().append(spreadsheetId=SPREADSHEET_ID, range=RANGE_NAME, valueInputOption=value_input_option, insertDataOption=insert_data_option, body=value_range_body)
    response = request.execute()

Answer 1

SCOPES must be of type list

SCOPES = ['https://www.googleapis.com/auth/spreadsheets', "https://www.googleapis.com/auth/drive.file", "https://www.googleapis.com/auth/drive"]

Side note: you have

.../auth/drive

And

.../auth/drive.file

/drive.file limits the API to work with only drive.file API but /drive opens up to all of the drive API. So you should pick one that fits your needs.

Side note 2: Based on the link you’ve provided, it mentions you need at least one of the API’s to work with spreadsheets, so you may not need all of them either.
