Error when calling Google Sheets API on Amazon Lamda using Python

Question

I am trying to create a Amazon Lambda python function that uses Google Sheets API to edit a sheet. I am using virtualenv and my script is compatible with python3.6. I have made sure that config.json and token.json are readable. See my code below:

from googleapiclient.discovery import build
from httplib2 import Http
from oauth2client import file, client, tools
import json

def lamda_handler(event, context):
    store = file.Storage("token.json")
    creds = store.get()
    if not creds or creds.invalid:
        flow = client.flow_from_clientsecrets("credentials.json", 'https://www.googleapis.com/auth/spreadsheets') # If modifying these scopes, delete the file token.json.

        creds = tools.run_flow(flow, store)
    service = build('sheets', 'v4', http=creds.authorize(Http()))

    # Call the Sheets API
    SPREADSHEET_ID = 'Google_Sheet_ID'
    RANGE_NAME = 'Sheet1!A1:A'
    result = service.spreadsheets().values().get(spreadsheetId=SPREADSHEET_ID,
                                                 range=RANGE_NAME).execute()
    value_range_body = {
        "majorDimension": "ROWS",
        "range": "Sheet1!A1:A",
        "values": [
            [
                "lamda"
            ],
            [
                898449
            ]
        ]
    }

    request = service.spreadsheets().values().update(spreadsheetId=SPREADSHEET_ID,
                                                     range=RANGE_NAME, valueInputOption='RAW', body=value_range_body)
    response = request.execute()


    values = result.get('values', [])

    if not values:
        return {
            "statusCode": 200,
            "body": json.dumps('No data found.')
        }
    else:
        return {
            "statusCode": 200,
            "body": json.dumps(values)
        }

I am getting following error every time I invoke the lambda function:

Any ideas what must be going wrong?

Answer 1

You can use MemoryCacheinstead:

class MemoryCache(Cache):
    _CACHE = {}

    def get(self, url):
        return MemoryCache._CACHE.get(url)

    def set(self, url, content):
        MemoryCache._CACHE[url] = content

Then when building service object, you add MemoryCache to cache attribute. So this is your code:

 service = build('sheets', 'v4', http=creds.authorize(Http()))

New code should be:

 service = build('sheets', 'v4', http=creds.authorize(Http()), , cache=MemoryCache())

Hope this help.
