@Seros I did a local checkout to your branch, installed dependencies and manually patched locally the changes in the module in your PR and I still see errors in the test execution.

Please, if this requires any additional steps not covered in the CI detail them so I can test.

I just did a clean checkout, executed the commands mentioned in the symfony.yml workflow, applied the changes from the module and run the tests. Everything looks fine. Which tests failed and what were the errors? Did you run php bin/console lexik:jwt:generate-keypair --skip-if-exists before?
