GCP Cloud Run service returning 502 on requests after recent deployment with Node.js
I'm confused about Could someone explain I'm experimenting with I've searched everywhere and can't find a clear answer. I've recently deployed a Node.js application to GCP Cloud Run, but I'm working with a `502 Bad Gateway` behavior when trying to access the service. The service seems to be running fine, as I can see it in the Cloud Console and the logs indicate that requests are hitting the service. However, the following behavior message is logged repeatedly: `2023/10/01 12:34:56 [behavior] 1#1: *1 upstream prematurely closed connection while reading response header from upstream`. My application is built using Express (version 4.17.1) and I'm using the `@google-cloud/functions-framework` library to handle the HTTP requests. Here is a simplified version of my code: ```javascript const express = require('express'); const app = express(); app.get('/', (req, res) => { res.send('Hello World!'); }); app.listen(process.env.PORT || 8080, () => { console.log('Server is running'); }); ``` In my Cloud Run service configuration, I've set the maximum instances to 5 and the timeout to 300 seconds. I've also ensured that the service is authenticated properly. I tried redeploying the service and double-checked the Dockerfile, which looks like this: ```Dockerfile FROM node:14 WORKDIR /usr/src/app COPY package*.json ./ RUN npm install COPY . . CMD [ "npm", "start" ] ``` I’ve also verified that the container is starting successfully, and I can see that the health checks are passing. Despite this, I keep hitting the `502 Bad Gateway` behavior when making requests from the browser or using `curl`. What could be causing this scenario, and how can I troubleshoot it further? Are there any particular configurations I might be missing for running Express on GCP Cloud Run? I'm working on a application that needs to handle this. Could someone point me to the right documentation? I'm coming from a different tech stack and learning Javascript. Thanks for your help in advance! I'd really appreciate any guidance on this. This is for a CLI tool running on Windows 11. Is there a simpler solution I'm overlooking? I've been using Javascript for about a year now. Thanks for your help in advance!
