Mule http proxy require double slashes (Failed to route event via endpoint)

Question

I have the mule config for http proxy as follows:

<pattern:http-proxy name="xxx-service-http-proxy">
    <http:inbound-endpoint address="http://localhost:8080" />
    <http:outbound-endpoint host="localhost" port="8589" />
</pattern:http-proxy>

now When I hit http://localhost:8080/swagger-ui.html. I get the message

Failed to route event via endpoint: DefaultOutboundEndpoint{endpointUri=http://localhost:8589swagger-ui.html

But when I hit http://localhost:8080//swagger-ui.html. Everything works as expected (needs double slashes). Can anyone point me out where I made a mistake.

The documentation from the Http proxy mentions nothing about that: https://docs.mulesoft.com/mule-runtime/3.5/http-proxy-pattern

Answer 1

I think the issue arises as there is no base path at all to append to.

Try to add the explicit path parameter to the outbound:

<http:outbound-endpoint host="localhost" port="8589" path="/" />

Or use the URL style for the outbound:

<http:outbound-endpoint address="http://localhost:8589" />
