Not able to hit external HTTP service via Apache Camel

I have a camel route similar to:

<camel:routeContext xmlns="http://camel.apache.org/schema/spring">
<route>
    <from uri="restlet:/v1/authentication/initiate?restletMethod=post&amp;restletBinding=#queryStringToHeadersRestletBinding"/>
    <to uri="http://xx.xx.xx.xx:20015/login"></to>
</route>

Now, after receiving the request from restlet, the camel processor instead of going to http://xx.xx.xx.xx:20015/login tries to hit http://localhost/v1/authentication/initiate which does not exist and thus I get 404 HTTPOperation failed like:

    Stacktrace
---------------------------------------------------------------------------------------------------------------------------------------
org.apache.camel.component.http.HttpOperationFailedException: HTTP operation failed invoking http://localhost/v1/authentication/initiate with statusCode: 404
    at org.apache.camel.component.http.HttpProducer.populateHttpOperationFailedException(HttpProducer.java:228) ~[camel-http-2.12.4.jar:2.12.4]
    at org.apache.camel.component.http.HttpProducer.process(HttpProducer.java:156) ~[camel-http-2.12.4.jar:2.12.4]
    at org.apache.camel.util.AsyncProcessorConverterHelper$ProcessorToAsyncProcessorBridge.process(AsyncProcessorConverterHelper.java:61) ~[camel-core-2.12.4.jar:2.12.4]

I am able to use the routes at other places successfully. But don't know why it is not hitting the intended destination url in this route definition. Please help.

Solution

Remove the CamelHTTP headers which the restlet may cause noise when calling the HTTP endpoint.
