在serverless.yml

Question

我正在使用serverless-graphql构建GraphQL Serverless API。

我已经建立了serverless.yml来尝试拥有多个GraphQL API，这些API使用不同的服务提供商角色。我希望能够获得序列中的第二个引用，以引用该角色的名称

例如 “ $ {self：custom.appSync [1] .serviceRole}” \

但是在部署API时会出错：

An error occurred: AuthenticatedAppSyncServiceRole - The specified value for roleName is invalid. It must contain only alphanumeric characters and/or the following: +=,.@_- (Service: AmazonIdentityManagement; Status Code: 400; Error Code: ValidationError; Request ID: 6b209659-8afc-11e9-aca7-1b89a9ac9c40).
