Hi,  
We are trying to share the aws lambda custom authorizer function across multiple API-Gateway, we are deploying this using serverless framework, while trying the same we got the below error.

**Error Message:**  
Logicai Id: “ArnLambdaPermissionApiGateway”  
status Reason: “Function not found: FunctionName (Service: AWSLambda; Status Code: 404; Error Code: ResourceNotFoundException; Request ID: \*\*\*\*)”

We are using serverless framework for the deploy, I have mentioned the reference url which we also referred.

FYI  
Shared Api gateway method:  
ref:[https://www.serverless.com/framework/docs/providers/aws/events/apigateway/#share-api-gateway-and-api-resources](https://www.serverless.com/framework/docs/providers/aws/events/apigateway/#share-api-gateway-and-api-resources)

Shared authorizers

Could any one please help us on this.I also shared the service.yml file and dummy project folder.
