Nested array object is returning an error

Nested array object is returning an error
I have an array property with a nested object, but when I try to do an insert it's returning an error.

To Reproduce

Steps to reproduce the behaviour:

Schema:

export const schema = {
  version: '0.0.1',
  indexes: {
    primary: { hash: 'pk', sort: 'sk' },
  },
  models: {

    Company: {
      pk: { type: String, value: 'company:${companyId}' },
      sk: { type: String, value: 'profile' },
      companyId: { type: String, uuid: 'ulid' },
      companyTitle: { type: String, required: true },
      createdAt: { type: Date, required: true },
      updatedAt: { type: Date, required: true },
    },
    CompanyEmployee: {
      pk: { type: String, value: 'company:${company.companyId}' },
      sk: { type: String, value: 'employee:${companyEmployeeId}' },
      companyEmployeeId: { type: String, uuid: 'ulid', required: true },
      company: {
        type: Object,
        schema: {
          companyId: { type: String, uuid: 'ulid' },
          companyTitle: { type: String },
        },
      },
      firstName: { type: String, required: true },
      lastName: { type: String, required: true },
      email: { type: String, required: true },
      selfAssessment: { type: Boolean, required: true },
      superiors: {
        type: Array,
        schema: {
          companyEmployeeId: { type: String, uuid: 'ulid', required: true },
          firstName: { type: String, required: true },
          lastName: { type: String, required: true },
        },
      },
      peers: {
        type: Array,
        schema: {
          companyEmployeeId: { type: String, uuid: 'ulid', required: true },
          firstName: { type: String, required: true },
          lastName: { type: String, required: true },
        },
      },
      subordinates: {
        type: Array,
        schema: {
          companyEmployeeId: { type: String, uuid: 'ulid', required: true },
          firstName: { type: String, required: true },
          lastName: { type: String, required: true },
        },
      },
      createdAt: { type: Date, required: true },
      updatedAt: { type: Date, required: true },
    },
  } as const,
};

When I create a new Employee:

await companyEmployeeModel.create({
  company: {
     companyId: '015ENZS901RKQ8IEQ09SX1C4VS',
     companyTitle: 'U85 Tech Ltd'
   },
   firstName: 'Arron',
   lastName: 'Finch',
   email: 'aron@email.co.uk',
   selfAssessment: false,
   superiors: [
    {
       companyEmployeeId: '015EP0BDFFASXRGR7DJZCIDF7S',
       firstName: 'John',
      lastName: 'Doe'
     }
   ],
  createdAt: 2021-12-03T11:38:16.964Z,
  updatedAt: 2021-12-03T11:38:16.964Z
});

It's returning an error:

TypeError: Cannot read property 'fields' of undefined
at Model.collectProperties (node_modules/dynamodb-onetable/dist/cjs/Model.js:965:28)
at Model.collectProperties (node_modules/dynamodb-onetable/dist/cjs/Model.js:975:26)
at Model.prepareProperties (node_modules/dynamodb-onetable/dist/cjs/Model.js:904:2)

field.block doesn't exist for superiors (which is an array)

There must be something wrong with the schema definition for superiors

The issue is you are using nested schemas on Array type items. This is not yet supported.

For now, comment out the schema. You won't get TS types for them, but when we do support it, hopefully soon, you can uncomment.

ok, thanks.

I would love to request this enhancement if it hasn't yet been added

oh, actually, i think it is working I take it back. The solution proposed here seems to work?
