I use keycloak version 21.1.1, I added new custom endpoint(test endpoint), here link to my sample project – https://github.com/j-developer-days/keycloak-rest-endpoint/tree/Option1
in github I described my problem in that path – custom_endpoint/options/1, there have 2 files(one with logs from keycloak, second with place, where I found that error)
