Validando usuário logado - org.jboss.resteasy.spi.UnhandledException: java.lang.IllegalArgumentException: id to load is required for loading

Ao implementar a mudança proposta no vídeo "Validando usuário logado" da aula 04, surgiu a exceção abaixo:

2021-04-09 18:30:09,925 ERROR [io.qua.ver.htt.run.QuarkusErrorHandler] (executor-thread-1) HTTP Request to /ordens failed, error id: ca8d4054-50cd-45a2-99c6-afcf97583315-1: org.jboss.resteasy.spi.UnhandledException: java.lang.IllegalArgumentException: id to load is required for loading

Tentei usar try-catch mas não deu certo,
