Assertion on ID only happen when value provided

[mjza]

I need to check the value has been provided for a Id, but I cannot define it as mandatory to be able to define auth:

categoryId: ID
    @assert(condition: ".length() > 1 && .matches(\"^\\w+$\")")
    @auth(
      rules: [
        { allow: owner, provider: userPools, operations: [create, update, read] }
        {
          allow: groups
          groups: ["Supers", "Admins", "Employees"]
          provider: userPools
          operations: [create, update, read]
        }
      ]
    )

But the assertion only file when user provides something, it means null is acceptable

Also for type String it happen only when value is provided, so length does not check in null

How can I check for not null?

categoryId: ID
    @assert(condition: ". != null")
    @auth(
      rules: [
        { allow: owner, provider: userPools, operations: [create, update, read] }
        {
          allow: groups
          groups: ["Supers", "Admins", "Employees"]
          provider: userPools
          operations: [create, update, read]
        }
      ]
    )

Does not work!

You just need to require it in GraphQL:

categoryId: ID!
    @auth(
      rules: [
        { allow: owner, provider: userPools, operations: [create, update, read] }
        {
          allow: groups
          groups: ["Supers", "Admins", "Employees"]
          provider: userPools
          operations: [create, update, read]
        }
      ]
    )

using exclamation mark after the field type.
