 */
export const handler = async (

    PhysicalResourceId: "MyCustomResource",
  });
};

cloud-aws-cloudformation-helpers-js's Issues

Property 'PhysicalResourceId' does not exist on type 'CloudFormationCustomResourceEvent'

When trying to return a response, I;d like to use the PhysicalID from the event, as it is part of a stack and will have a unique value for the name.

But for some reason i get the following TS error

Property 'PhysicalResourceId' does not exist on type 'CloudFormationCustomResourceEvent'. Did you mean 'LogicalResourceId'?
Property 'PhysicalResourceId' does not exist on type 'CloudFormationCustomResourceCreateEvent'

Migrate tests to Node.js test runner

Replace jest with the Node.js test runner (and tsmatchers for assertions if needed).
