Ошибка при привязке экземпляра службы в SAP CAP с использованием внешней службы

Question

В SAP CAP я следую этой ссылке примера блога для создания проекта CAP, использующего внешнюю службу. Однако во время развертывания в Clound Foundry я столкнулся с ошибкой ниже:

При развертывании произошла ошибка:

      Updating application "external-service-srv"...
Unbinding service instance "external-service-uaa" from application "external-service-srv"...
Binding service instance "external-service-uaa" to application "external-service-srv"...
Binding service instance "external-service-destination" to application "external-service-srv"...
Error while binding service instance "external-service-destination" to application "external-service-srv": Could not bind service "external-service-destination" to application "external-service-srv": 404 Not Found: Service instance external-service-destination not found. 
Proceeding with automatic retry... (3 of 3 attempts left)

Ниже фрагмент кода мои конфигурации:

Ошибка гласит, что экземпляр external-service-destination в mta.yaml не найден.

Обновление: мне удалось исправить проблему

Для тех, кто столкнулся с такой проблемой, обратите внимание на обновленный конфиг mta.yaml . Я следую этому руководству , и оно решило мою проблему во время развертывания BTP в Cloud Foundry.
