MuleSoft: Sending Form Parameters in a PUT Request

I'm trying to send a PUT request to my API with an object I stored in a variable 

<http:request config-ref="HTTP_Request_Configuration" path="muletest" method="PUT" metadata:id="ca84aa12-874e-654a-3214-5a9f16e04d09" doc:name="HTTP PUT /muletest" source="#[flowVars.muleTestFromCSV]">
    <http:request-builder>
        <http:uri-param paramName="id" value="#[flowVars.existingAppointment.get(0).id"/>
    </http:request-builder>
</http:request>

and I get this Error:

I use the same variable in a POST (#[flowVars.muleTestFromCSV]) and it works perfectly. I was assuming that PUT was like POST in terms of taking a Map as body but it doesn't give me the expected result. (From documentation):

Generate the Request Body with Content-Type:application/x-form-urlencoded Whenever the message payload is a Map, the connector automatically generates an HTTP request with the header Content-Type:application/x-www-form-urlencoded. The keys and values of the map in the payload are converted into form parameter keys and values in the body of the HTTP request.

Solution

  • Can you try to get rid of: 

    <http:request-builder>
    <http:uri-param paramName="id" value="#[flowVars.existingAppointment.get(0).id"/>
</http:request-builder>

    Set the Path same as like this:

    <http:request config-ref="httpConfig" path="thePath/1" method="PUT" doc:name="Update"/>
