We just run into a issue caused by differences between our GAE staging environment and our local one, based on Docker Compose.
The PHP 7.4 GAE runtime throws a critical error in a line that is only a notice for the local PHP 7.4 container. I'm guessing the issue has to do with different configuration but I have looked at the error reporting setting and even though they don't have the same values, it doesn't explain the problem.
Are the runtimes Docker images available to download, or can I easily convert whatever they are to something Docker understands? That way I could be using that environment locally too and avoid this kind of issue in the future.
Thank you!
