Answer 1

Using AppEngine's standard configuration with PHP 7.4 runtime, we encountered the same issue recently, and the value set for auto_prepend_file registering the library in php.ini in the standard setting no longer works. As we checked the sample repository, we discovered that they suggested registering error handlers manually as a workaround if php.ini cannot be accessed.

In our case, registering the error handler manually, resolved the issue.

# This works for files in the root of your project. Adjust __DIR__ accordingly.
require_once __DIR__ . '/vendor/google/cloud-error-reporting/src/prepend.php';

Take a look at the sample repository and verify that your configuration is set up correctly as well.
