某个服务无法调用其他服务

使用 cse-solution-service-engine 2.3.63 的版本
某个服务调用其他服务时会出现这样的报错,但是其他服务正常调用时都不会走到这个断点里面
为什么这个服务调用时会触发registerSchema呢

Commencez par SchemaLoader.registerSchema et suivez le chemin du schéma du consommateur à travers ConsumerSchemaFactory, SchemaMeta, SwaggerToClassGenerator, MethodConfig et CtType. Reproduisez l’échec avec cse-solution-service-engine 2.3.63 et examinez pourquoi registerSchema aboutit à la NullPointerException lors de la découverte des services. Le travail est terminé lorsque la cause est identifiée et qu’un correctif vérifié ou un test de régression est disponible.
