While the setup on my local machine (using Xampp with php PHP 7.3.2) works fine, trying to use it on AWS EC2 (using PHP 7.2) results in the following error:
message: "unserialize(): Error at offset 0 of 893 bytes" exception: "ErrorException" file: "/var/app/current/vendor/mpociot/versionable/src/Mpociot/Versionable/Version.php" line: 56
This happens apparently when calling getModel() on a version. Storing new versions seem to work without errors, I can see them in the database.
My guess is that this bug is due to the PHP version.
