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

Bắt đầu tại SchemaLoader.registerSchema và lần theo đường đi của consumer-schema qua ConsumerSchemaFactory, SchemaMeta, SwaggerToClassGenerator, MethodConfig và CtType. Tái hiện lỗi với cse-solution-service-engine 2.3.63 và kiểm tra lý do registerSchema gặp NullPointerException trong quá trình phát hiện service. Hoàn thành khi đã xác định được nguyên nhân và có một bản sửa đã được xác minh hoặc một regression test.
