User pool Lambda triggers not created

[martpet]

What could be the reason for Lambda triggers not being created? The user pool is created, the lambda functions as well, but the triggers are not present in the AWS console.

const userPoolLambdasProps = {
  environment: {
    usersTableName: usersTable.tableName,
    usersTableSchemaJson: JSON.stringify(usersTable.schema()),
  },
};

const postConfirmationLambda = new NodejsFunction(
  this,
  'PostConfirmLambda',
  userPoolLambdasProps
);

const postAuthenticationLambda = new NodejsFunction(
  this,
  'PostAuthLambda',
  userPoolLambdasProps
);

usersTable.grantReadWriteData(postConfirmationLambda);
usersTable.grantReadWriteData(postAuthenticationLambda);

const userPool = new UserPool(this, 'UserPool', {
  removalPolicy: RemovalPolicy.DESTROY,
  lambdaTriggers: {
    postConfirmationLambda,
    postAuthenticationLambda,
  },
});

Here is the code in context: https://github.com/martpet/trip-pics/blob/18fa3ca4dd86fbbcff5f2dec8e26a2451c27e7d8/backend/src/constructs/Cognito/Cognito.ts#L93

Initially I successfully created a single lambda trigger which appeared in the console, then I made some changes to other code and added a second trigger. Now none of the lambda triggers appear, even after I destroyed the stack and deployed from scratch..

It's my mistake, the correct shape of UserPoolTriggers is:

lambdaTriggers: {
  postConfirmation,
  postAuthentication,
}

I wish typescript warned me.
