GCP Cloud Run 503 Error: Service Unavailable for long running request

I have 4 API endpoints build in NodeJS, and deployed in GCP Cloud using docker image of the application which is as below:

My application, hits separate APIs, returns response and saves data in Cloud SQL.

FROM node:12

WORKDIR /usr/src/app

COPY package*.json ./

RUN npm install --only=production

# Copy local code to the container image.
COPY . ./

# Run the web service on container startup.
CMD [ "node", "app.js" ]

1 API takes around 1 min to return response and I get successful response back when trying from Postman and hitting the Cloud run URL

other 3 APIs takes 2 mins and other 20mins each to return response back and till that time I get error from Cloud run

503 Service Unavailable 
takes: 2 m 1.02 s 
478 B

Below are the configuration given :

Memory allocated: 8 GB
CPU allocated: 4 
Maximum request per container: 20
Request timeout: 3600 seconds

NOTE: I am only hitting one request at a time

What can be the problem ? I increased concurrency but that didn't work. For my application in Cloud Function service won't work as timeouts is 9 mins.

Which service I can use in GCP for this kind of work?

I found that the problem was with NodeJS request timeout which was 120 seconds default and with help of below link I got my issue fixed.

https://github.com/GoogleCloudPlatform/esp-v2/issues/438

So I have to do the following in my code:

I can set the timeout either for entire server:

var server = app.listen();
server.setTimeout(500000); // In milliseconds

or just for specific route:

app.post('/xxx', function (req, res) {
   req.setTimeout(500000);
});

This resolved the issue.
