AWS CloudFormation с вложенным приложением sar

Question

Я пытаюсь развернуть шаблон sam на AWS, я использую другой AWS :: Serverless :: Application в качестве ресурса. У меня есть sns topi c в моем шаблоне с именем AlarmTopi c, и я хочу передать topi c arn во вложенный стек в параметре SnsPublisherTopicExport, но я получил следующую ошибку:

Embedded stack arn:aws:cloudformation:us-east-1:883750447417:stack/sam-app-awssnstoslackpublisher-1GYZREGDLZ3WW/06b95020-76a9-11ea-b351-1288d43a03c2 was not successfully created: No export named arn:aws:sns:us-east-1:883750447417:sam-app-AlarmTopic-5GQY4KDA7Y06 found
