Apigee response not getting sent to angular application

[#1]

I have an angular that sends calls to Apigee. After tracing the calls i can see that a response is returned. However the client does not get the response. I have no idea what i could be missing in this instance.

I have set up CORS correctly on Apigee and can see the options preflight response getting called successfully. The issue really is on the second call, a response is returned but the client receives null data

Please open the Developer Javascript console in browser and check the Network . Please check the response code and if possible post the bundle to look into it further.

On the browser this is what i am getting. No 'Access-Control-Allow-Origin' header is present on the requested resource. Originis therefore not allowed access. i have set up cors correctly. Here are my configurations

<AssignMessage async="false" continueOnError="false" enabled="true" name="Add-CORS">
    <DisplayName>Add CORS</DisplayName>
    <Properties/>
    <Add>
        <Headers>
            <Header name="Access-Control-Allow-Origin">*</Header>
            <Header name="Access-Control-Allow-Headers">origin, x-requested-with, accept, Authorization, ApiKey, Content-Type, apikey, authorization, content-type,access-control-allow-origin</Header>
            <Header name="Access-Control-Max-Age">3628800</Header>
            <Header name="Access-Control-Allow-Methods">GET, OPTIONS</Header>
        </Headers>
    </Add>
    <IgnoreUnresolvedVariables>true</IgnoreUnresolvedVariables>
    <AssignTo createNew="false" transport="http" type="request"/>
</AssignMessage>

Here is my proxy endpoint
