説明

First - thank you so much for creating and working on this project.

I've deployed to Heroku. Most of the time pdf is generated, sometimes there is an error and entire node server crashes.

Here is the log: url_to_pdf_api_error-01-25-2018.log

Is there a good way to debug this problem? Currently it crashes around ~20% of the time. I was running on "hobby" initially, but had same results on 1x and 2x instance types.

調査方針: The issue reports intermittent crashes when rendering PDF from HTML via POST. The user has provided a log file link. To debug, start by examining the log file content to identify crash patterns. Check the rendering code in the repository, likely using Headless Chrome or similar. Look for unhandled promise rejections or memory leaks. Consider adding more robust error handling and ensure all promises are handled. Test with sample HTML payloads to isolate the issue. Also, review recent commits or similar issues for potential fixes.
