In trying to convert an existing SOAP API to REST in Apigee Edge receiving this error message...Manually setting up API with a path parameter. Any help appreciated. Links or suggestions. Thanks.

It seems you have attached the policy in the request flow where the response is not available.

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<XMLToJSON async="false" continueOnError="false" enabled="true" name="XML-to-JSON-1">
    <DisplayName>XML to JSON-1</DisplayName>
    <Properties/>
    <Format>yahoo</Format>
    <OutputVariable>response</OutputVariable>
    <Source>response</Source>
</XMLToJSON>

Normally it looks like above when you try to convert response from xml to json. In this case the content type should be xml in the response.

"<Source>response</Source>" this is the part which creates error for you.

BTW, here's a screencast/video explaining how to do this.

Older video, and the Apigee UI has been updated since then. But the approach illustrated in the video is still relevant.
