Not able to call cloud firestore and cloud task api from app engine flexible environment

[ASHIK RANJAN]

When calling the cloud task and cloud firestore API from app engine flexible environment running flask application, I am getting no error/response for a long time and it gets timed out.

But same API call is working fine from another server outside of google cloud using the same service account.

Can you please help me if the above two API can be called from the app engine flexible environment or if some settings need to be changed?

Hi,

Would you be able to please provide a screenshot or full log the error message/response you are seeing? This will help to better visualize and diagnose as to why these are occurring in the first place. Better yet, I would suggest to open an public issue tracker ticket [1] to look into your inquiry further.

Would you be able to provide a little more details regarding your implementation as well as application architecture? This will help to better visualize how these components are integrated, as well as provide possible alternatives for the bottlenecks that your app is experiencing.

I am using the flask application on the google app engine flexible environment.

1. I want to create a task whenever some URL has been hit by a user and queues should hit the google app engine endpoint for executing the task. For example, I am appending the code here

The same code is working fine and creating a task if executed from another server

import json
import datetime
from google.cloud import tasks_v2beta3
from google.protobuf import timestamp_pb2

import json
import datetime
from google.cloud import tasks_v2beta3
from google.protobuf import timestamp_pb2


class CloudTaskManager:
    def __init__(self):
        self.client = tasks_v2beta3.CloudTasksClient()

    def create_task(self, project, queue, location, payload=None, in_seconds=5):
        parent = self.client.queue_path(project, location, queue)

        task = {
            'app_engine_http_request': {
                'http_method': tasks_v2beta3.HttpMethod.POST,
                'relative_uri': '/api/v1/rating/cloud_task_handler',
                'headers': {
                    'Content-Type': 'application/json',
                    'Org_Name': 'organization1'
                },
                'body': json.dumps(payload).encode()
            }
        }

        if in_seconds is not None:
            d = datetime.datetime.utcnow() + datetime.timedelta(seconds=in_seconds)
            timestamp = timestamp_pb2.Timestamp()
            timestamp.FromDatetime(d)
            task['schedule_time'] = timestamp

        response = self.client.create_task(parent=parent, task=task)
        return response

2. Another case is that I want to use cloud firestore API that is in native mode and the code snippet are as below.

   cred = credentials.Certificate('name.json')  
    # cred = credentials.ApplicationDefault()
    if not firebase_admin._apps:
        firebase_admin.initialize_app(cred, {
          'projectId': 'project-id',
        })
    db = firestore.client()
    collection_refs = db.collection('collection-name')
    documents = collection_refs.stream()
    for doc in documents:
        return doc.to_dict()

Hi, 

Thanks for providing this information about your app.

Regarding your error, are the timeouts still reoccurring? How often do these timeouts occur (daily, intermittently, etc.)? It would also be helpful to have a screenshot of the error message; this will provide us details of the necessary steps for mitigating this issue for your application.

For readability and troubleshooting purposes, it would be beneficial to bring this issue to the App Engine team via Issue tracker as provided from the previous message. Have you managed to open up a public issue tracker ticket already for your issue?

Basically I not getting any error when calling the required function to create a task or the function for crud on firestore.

After a certain time, periods request is killed by the server(app engine).

No, I have not created public issues for the same.
