我使用JsonSchema.Net.Generation生成了JSON模式，我的模式类如下：

class PaymentInitiationSchema
{
    [Required]
    [JsonPropertyName("type")]
    public string Type { get; set; }

    [Required]
    [JsonPropertyName("actions")]
    public string[] Actions { get; set; }

    [Required]
    [JsonPropertyName("locations")]
    public string[] Locations { get; set; }

    [Required]
    [JsonPropertyName("instructedAmount")]
    public InstructedAmount InstructedAmount { get; set; }

    [Required]
    [JsonPropertyName("creditorName")]
    public string CreditorName { get; set; }

    [Required]
    [JsonPropertyName("creditorAccount")]
    public CreditorAccount CreditorAccount { get; set; }

    [Required]
    [JsonPropertyName("reemitanceInformationUnstructured")]
    public string ReemitanceInformationUnstructured { get; set; }
}

class InstructedAmount
{
    [Required]
    [JsonPropertyName("currency")]
    public string Currency { get; set; }

    [Required]
    [JsonPropertyName("amount")]
    public decimal Amount { get; set; }
}

class CreditorAccount
{
    [Required]
    [JsonPropertyName("iban")]
    public string Iban { get; set; }
}

它是生成的模式：

{
   "type":"object",
   "properties":{
      "type":{
         "type":"string"
      },
      "actions":{
         "$ref":"#/$defs/array"
      },
      "locations":{
         "$ref":"#/$defs/array"
      },
      "instructedAmount":{
         "type":"object",
         "properties":{
            "currency":{
               "type":"string"
            },
            "amount":{
               "type":"number"
            }
         },
         "required":[
            "currency",
            "amount"
         ]
      },
      "creditorName":{
         "type":"string"
      },
      "creditorAccount":{
         "type":"object",
         "properties":{
            "iban":{
               "type":"string"
            }
         },
         "required":[
            "iban"
         ]
      },
      "reemitanceInformationUnstructured":{
         "type":"string"
      }
   },
   "required":[
      "type",
      "actions",
      "locations",
      "instructedAmount",
      "creditorName",
      "creditorAccount",
      "reemitanceInformationUnstructured"
   ],
   "$defs":{
      "array":{
         "type":"array",
         "items":{
            "type":"string"
         }
      }
   }
}

我创建了示例函数来验证给定的JSON：

static bool IsValid(string requestedAuthorizationDetails, JsonSchema authorizationDetailsSchema)
{
    try
    {
        JsonDocument.Parse(requestedAuthorizationDetails);
    }
    catch
    {
        return false;
    }

    var result = authorizationDetailsSchema.Validate(requestedAuthorizationDetails, new ValidationOptions
    {
        OutputFormat = OutputFormat.Detailed
    });

    Console.WriteLine(result.Message + " at " + result.SchemaLocation.Source);

    return result.IsValid;
}

这个调用总是false：

var schemaBuilder = new JsonSchemaBuilder();
var schema = schemaBuilder.FromType<PaymentInitiationSchema>().Build();

Console.WriteLine(IsValid(@"{
      ""type"": ""payment_initiation"",
      ""actions"": [
         ""initiate"",
         ""status"",
         ""cancel""
      ],
      ""locations"": [
         ""https://example.com/payments""
      ],
      ""instructedAmount"": {
         ""currency"": ""EUR"",
         ""amount"": 123.50
      },
      ""creditorName"": ""Merchant A"",
      ""creditorAccount"": {
         ""iban"": ""DE02100100109307118603""
      },
      ""remittanceInformationUnstructured"": ""Ref Number Merchant""
   }", schema));

而且误差也总是一样的：
值为"string"，但在#/type处应为"object"
真的不明白为什么。我想可能是JSON方案顶部的type和作为必需参数的type之间有冲突。但是即使我从参数中删除了type，仍然会出现同样的错误。
有什么不对吗？
