[keycloak-dev] How to do my pull request successfully

Hello comunity, I am trying to understand the process to contribute to the project. A few days ago I did my first pull request but some errors occurred while running the tests. I do not understand the error very well, what is the process here ?, Where can I find more information ?, This is the channel where I should ask about this? https://github.com/keycloak/keycloak/pull/4219 Thanks
