Can't parse: JSON recipe that has a `PropertyValue` as a `recipeIngredient`

[JonathanHarford]

Describe the bug
Recipya errors when given a JSON recipe that has a PropertyValue as a recipeIngredient:

panic: interface conversion: interface {} is map[string]interface {}, not string

Screenshots

Desktop (please complete the following information):

• OS: Mac Intel
• Browser Zen 1.16.4b (Firefox 143.0.4) (64-bit)
• Version 1.16.4b

Additional context
I may have my recipya instance badly set up, but when the parsing fails, it shows as a websocket error and I get logged out!
Uploads OK:

{
  "@context": "https://schema.org",
  "@type": "Recipe",
  "name": "Dry Toast",
  "description": "When you can't keep anything down",
  "recipeYield": "1 servings",
  "prepTime": "PT3M",
  "totalTime": "PT3M",
  "recipeCategory": "sandwich",
  "recipeIngredient": ["1 slice whole wheat bread"],
  "recipeInstructions": [
    {
      "@type": "HowToStep",
      "text": "Toast for 2 minutes."
    }
  ]
}

Breaks:

{
  "@context": "https://schema.org",
  "@type": "Recipe",
  "name": "Dry Toast",
  "description": "When you can't keep anything down",
  "recipeYield": "1 servings",
  "prepTime": "PT3M",
  "totalTime": "PT3M",
  "recipeCategory": "sandwich",
  "recipeIngredient": [
    {
      "@type": "PropertyValue",
      "name": "whole wheat bread",
      "value": {
        "@type": "QuantitativeValue",
        "value": "1",
        "unitText": "slice"
      }
    }
  ],
  "recipeInstructions": [
    {
      "@type": "HowToStep",
      "text": "Toast for 2 minutes."
    }
  ]
}

This is closely related to #407
I'm filing this as a bug because Recipya claims to be able to import recipes that adhere to the Recipe Schema.

Thank you for letting me know. The spec updated the expected values for recipeIngredient between August 30 2025 and September 9 2025.

I'll update the recipe-schema crate over at recipya-rs when I'll have time.

The schema parsing has been updated to the latest version of schema.org in recipya-rs. Here is the result when the user previews the breaking JSON above and then adds the recipe to their collection:
