AWS SAM : Importing AWS API gateway resource in another template gives error : Reason: Transform AWS::Serverless-2016-10-31 failed with: Internal transform failure. #1335
Description
In the first SAM template, I want to create an API Gateway and a lambda function which uses this API gateway.
Here is the snippet -
First SAM template -
Resources: MyApi: Type: AWS::Serverless::Api Properties: Name: Rainmaker AWS Api Gateway StageName: !Ref StageName Cors: "'*'" Outputs: RainmakerApiRestApiId: Description: 'API Gateway ARN for my AWS API Gateway' Value: Ref: MyApi Export: Name: !Sub "${AWS::StackName}-MyApi" MyApiRootResourceId: Value: !GetAtt MyApi.RootResourceId Export: Name: MyApi-RootResourceId I am trying to export this API gateway resource, from the first template.
I want to use this API gateway resource in another SAM template, using import statement.
Here is the snippet in the second SAM template.
Parameters: StageName: Type: String Default: dev MyBaseStackName: Description: Name of the base stack with all infra resources Type: String Default: first-stack Resources: MyFunction: Type: AWS::Serverless::Function Properties: FunctionName: MyFunctionName CodeUri: ../../../bin/handlers/ Handler: myfunctionname Events: MyHTTPEvent: Type: Api Properties: RestApiId: Fn::ImportValue: !Sub "${MyBaseStackName}-MyApi" Path: /authorize Method: get Auth: Authorizer: NONE When I deploy the second SAM template, I am getting below error -
Error: Failed to create changeset for the stack: esp-git-user, ex: Waiter ChangeSetCreateComplete failed: Waiter encountered a terminal failure state Status: FAILED. Reason: Transform AWS::Serverless-2016-10-31 failed with: Internal transform failure.
Is there any good example which explains exporting API gateway resource from the first SAM template and then using it in the second SAM template.
