Working in the standard signup.ts and added name to create user. Seems to work alright, but when I deploy i get a warning in this line:

const { email, password, name } = event.data

Warnings:

signup.ts (25,17): Type '{}' has no property 'email' and no string index signature.
signup.ts (25,24): Type '{}' has no property 'password' and no string index signature.
signup.ts (43,68): Type '{}' has no property 'name' and no string index signature.

further above there are some interfaces that describe the shape of

Event

. you need to adjust it.
