I’m scratching my head over a weird Puppeteer issue. It’s working fine on my computer but acting up on Google App Engine (GAE).
When I run my script to grab screenshots, some websites (especially Shopify ones) come out wonky. The pics and icons are MIA, and I’m getting fallback stuff instead.
Here’s the kicker:
Works great locally
Same exact setup on both sides (Puppeteer, Node, Chromium versions)
Using the same build for testing and GAE
I’ve got all the bells and whistles in my script - autoscroll, delays, you name it. But GAE seems to ignore some resource requests completely.
I’ve been comparing request headers between local and GAE. It looks like GAE isn’t even trying to fetch certain resources.
Any ideas what could be causing this? It’s driving me nuts!
I’ve encountered similar issues when deploying Puppeteer-based projects to cloud environments. One potential culprit could be GAE’s default security policies restricting certain network requests. Have you considered configuring a VPC connector for your GAE instance? This might allow more flexibility in outbound connections.
Another avenue to explore is the puppeteer-cluster library. It’s designed to handle distributed environments better and might mitigate some of the resource-fetching issues you’re experiencing.
Lastly, it might be worth investigating if there are any differences in how GAE handles HTTPS requests compared to your local environment. Sometimes, subtle discrepancies in SSL/TLS configurations can lead to unexpected behavior in resource loading.
hey there, sounds like a real headache! have u tried messing with the network settings in puppeteer? sometimes GAE can be finicky with connections. maybe try setting a custom user-agent or adjusting the timeout? also, double-check if GAE is blocking any resources. good luck troubleshooting!
I’ve run into this exact problem before and it was quite frustrating. After several days of troubleshooting, I discovered it stemmed from GAE’s sandbox restrictions—specifically, the Content Security Policy (CSP). I solved the issue by explicitly allowing the necessary domains in the app.yaml file and tweaking the Puppeteer launch options to circumvent CSP. I also implemented detailed console logging for each resource request to pinpoint what was being blocked and modified my script to better handle GAE’s request timeout limits. Although it was a hassle, these adjustments eventually led to smooth operation. I hope this insight proves useful.
