Access the Status Code or a request made using <send-request>

Question

I'm making a request using the <send-request> policy, and I need to check the Status Code of the request. To do this, I'm trying to access the StatusCode property of the response-variable-name. However, when using this code -

context.Variables["LogFailedEvent"].StatusCode

I'm seeing this error -

Error in element 'set-body' on line 83, column 4: 'object' does not contain a definition for 'StatusCode' and no extension method 'StatusCode' accepting a first argument of type 'object' could be found

According to the docs -

The response-variable-name attribute is used to give access the returned response. The name defined in this property can be used as a key into the context.Variables dictionary to access the IResponse object.

Either I'm misinterpreting what is in the docs, or the docs are wrong. Is anyone able to suggest a solution?

Relevant section from policy

<choose>
    <when condition="@(context.Response.StatusCode != 201 && context.Response.StatusCode != 202)">

        <send-request mode="new" response-variable-name="LogFailedEvent" timeout="20" ignore-error="true">
            <set-url>@(string.Format("{0}{1}?code={2}&statusCode={3}&statusReason={4}&message={5}", "{{BVT_LogEventsFailedFunction_Url}}", "{{BVT_LogEventsFailedFunction_Template}}", "{{BVT_LogEventsFailedFunction_Code}}", context.Response.StatusCode, context.Response.StatusReason, context.Response.Body.As<string>()))</set-url>
            <set-method>POST</set-method>
            <set-header name="Content-Type" exists-action="override">
                <value>application/json</value>
            </set-header>
            <set-body>@(context.Request.Body.As<string>())</set-body>
        </send-request>

        <set-body>@(string.Format("{{\"message\":\"event captured by LogFailedEvents\",\"requestId\":\"{0}\",\"statusCode\":\"{1}\",}}", context.RequestId.ToString(), context.Variables["LogFailedEvent"].StatusCode))</set-body>

    </when>
</choose>

You need to cast it:

((IResponse)context.Variables["LogFailedEvent"]).StatusCode

Also, since youre setting ignore-error="true" you might want to check first is Variables contains this key at all, since in that case this variable is notcreated at all if request fails.

Access the Status Code or a request made using <send-request>
