apparently this is invalid:

const userPool = auth.node.defaultChild as cognito.CfnUserPool;
  
  userPool.lambdaConfig = {
    customEmailSender: {
      lambdaArn: props.cognitoEmailSender.functionArn,
    },
  };

I get this error:

TypeError: Cannot set property 'lambdaConfig' of undefined

. any ideas how I’d set this? TypeScript did give the OK here.. but apparently

defaultChild

doesn’t exist in this case

Can you show a bit more about where

auth.node

is coming from

auth

is an instance of

sst.Auth

I think maybe you want to try this:

auth.cognitoUserPool!.addTrigger

it’s not a trigger though, I don’t think. it doesn’t come up in autocomplete when you’re adding triggers in

new sst.Auth()

Ah I see
