REST API调用的错误信息不显示在B2C自定义策略中。

Question

我的自定义策略中有一个自断的技术配置文件，它有一个验证技术配置文件，这是一个REST API（azure函数）调用。我不是直接从策略中调用 azure 函数，从策略中会调用 azure APIM，APIM 会将请求传递给 azure 函数。

我面临的问题是，当我的函数返回自定义的错误信息时，它并没有在policy中按预期显示。

return new OkObjectResult(new ResponseContentModel
      {
       userMessage = "Sorry, Please provide valid information ",
       status = 409,
       retryCounter = data.RetryCounter
     });

我的技术配置文件如下。

<TechnicalProfile Id="Registration">
          <DisplayName>Email signup</DisplayName>
          <Protocol Name="Proprietary" Handler="Web.TPEngine.Providers.SelfAssertedAttributeProvider, Web.TPEngine, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" />

REST API验证技术资料如下：

                  <OutputClaim ClaimTypeReferenceId="isFound" />
                </OutputClaims>
                <UseTechnicalProfileForSessionManagement ReferenceId="SM-Noop" />
            </TechnicalProfile>

在用户界面上显示的错误信息是：

在步骤'5'中指定的理赔交换'API-Validate-UserInfo'返回HTTP错误响应，代码为'BadRequest'，原因为'Bad Request'。

关于这个函数，我使用的是 .net core 3.1 和函数运行时版本为 ~3

找到了提到的问题 本条。 需要在响应消息中加入版本版本、状态和用户消息是错误响应消息的必选字段。

{
  version = "1.0.0",
  userMessage = "Sorry, Something happened unexpectedly. Please try after sometime.",
  status = 409,
 }
