使用 GraphQl 突变和 Angular 11 客户端 (Apollo) 在 Symfony 5 + ApiPlatform v2.6 中进行翻译，我将介绍以下工作流程：
执行步骤 1 时一切正常，使用 Promise.all() 获取 IRI 并将其作为数组传递（这是 GraphQl 突变的请求参数）。
这是接收一些必需参数和 IRI 数组（之前创建的翻译）的突变。请注意，没有因格式、拼写错误或参数名称/类型而引发错误或异常。
mutation createRecipeSteps($cookOrder: Int!, $translations: [String]) {
createRecipeSteps(input: {cookOrder: $cookOrder, translations: $translations}) {
recipeSteps {
id
}
}
}
// set of variables used
{
"translations": [
"/api/recipe_steps_translations/1863",
"/api/recipe_steps_translations/1864",
"/api/recipe_steps_translations/1865"
],
"cookOrder": 0
}
发送突变后，我收到以下异常：

按照建议，我尝试使用对象更改区域设置表示（es | en）的键，但我得到了相同的异常。
如果我按要求传递一个字符串数组，为什么会出现此错误。 预先感谢！
我只是从您处理翻译和错误的事实中猜测，区域设置字符串应该是数组键，示例中的第一个键将是
int 0所以在 php 中它可能期待这样的associative字符串数组：
[
"en" => "/api/recipe_steps_translations/1863",
"es" => "/api/recipe_steps_translations/1864",
"fr" => "/api/recipe_steps_translations/1865"
]
在 js 中定义数据将如下所示：
let translations = {
en: "/api/recipe_steps_translations/1863",
es: "/api/recipe_steps_translations/1864",
fr: "/api/recipe_steps_translations/1865"
}
JSON 表示为：
JSON.stringify(translations)
// or
"{\"en\":\"/api/recipe_steps_translations/1863\",\"es\":\"/api/recipe_steps_translations/1864\",\"fr\":\"/api/recipe_steps_translations/1865\"}"
