my proxy cinfiguration is :

<proxy name="stripe" transports="https http" startOnLoad="true" trace="disable">
        <target>
            <endpoint>
                <address uri="https://api.stripe.com/v1"/>
            </endpoint>
            <inSequence>
                <log level="full" separator="SSSSSSSSSSSSSSSSSs">
                    <property name="HTTP_METHOD" value="post"/>
                </log>
                <send/>
            </inSequence>
            <outSequence>
                <log level="full" separator=", ooooooooooo"/>
                <send/>
            </outSequence>
        </target>
    </proxy>

Curl command to execute the request:

curl https://localhost:8243/services/stripe/charges/ch_iQs4noWTm7J5Kk/refund  -u Ixj3FHIiQSFWrzb4VNSxoThKVk3IXpBF --insecure -X POST

What is the content type of the POST request. This error happens when you don't have the message fomatter and builder for the content type used.

Ok. Then in the axis2.xml, please check whether you have JSON Builders and formatters for the content type application/json. – Kasun Indrasiri Jun 17 '12 at 15:32

I spent 7 days on this bug. There are many different answers to this bug.

It's happened when your web service return to wso proxy empty body or incorrect content-length or something else (there are many things).

But in my case the problem was that my webservice on my route '/' (POST method) return 400 code if content-length equal 0. I think wso2 proxy by first step send some data to my webservice with zero content-length header or without this header and my webservice just "block" this and return 400 code.
