Question about "items" property must be present if "type" is an array

[rmcsharry]

Hi,

I thought an array can be defined on a model like this:

@property.array(Address, { name: 'addresses' })
addresses: Address[];

and that loopback infers the items for the json Schema because it's an array property.

But when our tests run, it throws this error:

"items" property must be present if "type" is an array'

because of !json.items on this line

loopback-next/packages/openapi-v3/src/json-to-schema.ts

Line 66 in debd55e

if (json.type === 'array' && !json.items) {

If I change the definition to this, it's fine:

  @property.array(Address, {
    name: 'addresses',
    jsonSchema: {
      type: 'array',
      items: { type: Address },
    },
  })
  addresses: Address[];

This means changing a lot of properties all across our codebase. This should not be necessary, right? Or is Loopback not able to infer the items property without defining it like this?
