I am trying to use code from the document

Adding Lambda authorizatino

(link) While developing locally

sst start

I am returning following data from the authorizer lambda.

{
  principalId: 'abc',
  policyDocument: { Version: '2012-10-17', Statement: [ [Object] ] },
  context: { stringKey: 'stringval', numberKey: 123, booleanKey: true }
}

Event object in api handler should contain principalId in

event.requestContext.authorizer.principalId

field. But, the `event.requestContext.authorizer`` object looks like following. (Missing principalId)

{
  lambda: { booleanKey: 'true', numberKey: '123', stringKey: 'stringval' }
}

Am I missing something, here?

Can’t be of much help, but my authorizor response looks like this:

{
    principalId: verified.sub,
    policyDocument: getPolicyDocument('Allow', params.methodArn),
    context,
  }

So I think you can probably rule out the syntax being wrong. I assume if the policy doc was invalid, then nothing would work. And I access the

principalId

at the same key and it works for me The only difference I can think of is that I am using ApiGatewayV1 not V2

When using APIGWV2 with response format 2.0 the response can be a simple type type or an iam policy. A simple response does not contain

principalId

. You can configure it like:

const defaultAuthorizer = new HttpLambdaAuthorizer({
        responseTypes: [HttpLambdaResponseType. SIMPLE,HttpLambdaResponseType.IAM],
         resultsCacheTtl: cdk.Duration.seconds(60),
         ....
        })
