String field with limited possible values (list): “Value did not match any allowed values”

[patrulea]

I’m trying to set a string-type field with a dropdown for possible values (list). Though, the input appears to be invalid as it’s expecting a string value but instead getting an object ([object Object]) and it prevents saving the user input.

My custom field type looks like this:

// localeSelect.js
export default {
  name: "localeSelect",
  type: "string",
  options: {
    list: [
      {
        title: "English (United States)",
        value: "en_US"
      },
      {
        title: "Spanish (Latin America)",
        value: "es_LA"
      }
    ]
  }
}

// documentSchema.js
{
  name: "locale",
  type: "internationalizedArrayLocaleSelect"
}

Note how there is no custom field validation in place. The string/list field is performing its inherent value check.
