aws serverless - exporting output value for cognito authorizer - aws-lambda

Question

I'm trying to share cognito authorizer between my stacks for this I'm exporting my authorizer but when I try to reference it in another service I get the error
Trying to request a non exported variable from CloudFormation. Stack name: "myApp-services-test" Requested variable: "ExtApiGatewayAuthorizer-test".
Here is my stack where I have authorizer defined and exported:
CognitoUserPool:
Type: AWS::Cognito::UserPool
Properties:
# Generate a name based on the stage
UserPoolName: ${self:provider.stage}-user-pool
# Set email as an alias
UsernameAttributes:
- email
AutoVerifiedAttributes:
- email
ApiGatewayAuthorizer:
Type: AWS::ApiGateway::Authorizer
Properties:
Name: CognitoAuthorizer
Type: COGNITO_USER_POOLS
IdentitySource: method.request.header.Authorization
RestApiId: { "Ref": "ProxyApi" }
ProviderARNs:
- Fn::GetAtt:
- CognitoUserPool
- Arn
ApiGatewayAuthorizerId:
Value:
Ref: ApiGatewayAuthorizer
Export:
Name: ExtApiGatewayAuthorizer-${self:provider.stage}
this is successfully exported as I can see it in stack exports list from my aws console.
I try to reference it in another stack like this:
myFunction:
handler: handler.myFunction
events:
- http:
path: /{userID}
method: put
cors: true
authorizer:
type: COGNITO_USER_POOLS
authorizerId: ${myApp-services-${self:provider.stage}.ExtApiGatewayAuthorizer-${self:provider.stage}}
my env info

Answering my own question
it looks like I should have imported by output name not output export name, which is bit weird and all the docs I have seen point to export name, but this is how I was able to make it work
replaced this -
authorizerId:${myAppservices-${self:provider.stage}.ExtApiGatewayAuthorizer-${self:provider.stage}}
with -
authorizerId: ${myApp-services-${self:provider.stage}.ApiGatewayAuthorizerId}

If you come across Trying to request a non exported variable from CloudFormation. Stack name: "myApp-services-test" Requested variable: "ExtApiGatewayAuthorizer-test"., when exporting profile i.e.,
export AWS_PROFILE=your_profile
It must be done on the terminal window where you are doing sls deploy not on another terminal window. It is a silly mistake but I don't want anyone else waste their time around that
