**API Platform version(s) affected**: 3.2.20 <!-- Warning: if your version is 2.7 we ask you to try the 3.0 version. If the bug is present there we will fix it. If the bug is due to old 2.6 behavior we can't fix it. In that last case we recommend to either upgrade to 3.0 or to temporarily replace concerned service with your own. --> **Description** Refer to https://github.com/symfony/symfony/issues/54478. I do not use GraphQL, and the issue still exists in 3.2.20. The only work-around I can find is to hack the priority in `services.yaml`. **How to reproduce** <!-- Code and/or config needed to reproduce the problem. If it's a complex bug, create a dedicated GitHub repository. --> Here is a repository with a [problem replicator](https://github.com/gnito-org/api-backed-enum-replicator). **Possible Solution** <!--- Optional: only if you have suggestions on a fix/reason for the bug. --> **Additional Context** <!-- Optional: any other context about the problem: log messages, screenshots, etc. -->
