- Due to
@keycloak/keycloak-admin-clientpackage,nestjs-keycloak-admincan't support CommonJS at the moment. The team behindkeycloak-admin-clientmade the decision to have a breaking change and support CommonJS. Please refer to this Github issue for more information about their decision-making process. - You need to switch to ESM to run this package without any issues. Please refer to this Github gist for more information.
