What happended?

Trying to query inventory items and their inventory levels using the following query

const inventoryQuery =  remoteQueryObjectFromString({
        entryPoint: "inventory_items",
        fields: ["*", "inventory_levels.*"],
        filters: {
          variants: {
            id: item.product_variant_id,
          },
        },
      })

Which results in the error:

error:   Entity 'InventoryItem' does not have property 'inventory_levels'

Looking into the source code, it looks like the actual database field is location_levels

medusa/packages/modules/inventory/src/models/inventory-item.ts

Line 122 in 7794faf

location_levels = new Collection<Rel<InventoryLevel>>(this)

When I use this query

const inventoryQuery =  remoteQueryObjectFromString({
        entryPoint: "inventory_items",
        fields: ["*", "location_levels.*"],
        filters: {
          variants: {
            id: item.product_variant_id,
          },
        },
      })

I get a valid query but typescript yells at me (not sure where the types are defined for this)

I believe either the Model schema or Types should change to be in sync

Expected behavior

InventoryItem.inventory_levels

Actual behavior

InventoryItem.location_levels
