Doubled domain/host in REST client's requests

[dawidnowakowski]

Hi all.
Today's morning I noticed a crucial issue introduced to the application without any code changes. In my Quarkus app I have a REST client to communicate with an external webservice.

Quarkus 3.20.0

pom.xml

<dependency>
            <groupId>io.quarkus</groupId>
            <artifactId>quarkus-rest-client-jaxb</artifactId>
</dependency>

application.properties

%dev.quarkus.rest-client.webservice-api.url=http://sample.domain.com/path/path2
%dev.quarkus.rest-client.webservice-api.scope=jakarta.inject.Singleton

RestClient class is annotated as follows:

@RegisterRestClient(configKey = "webservice-api")

Everything was working perfectly fine until today's morning. After launching the app I noticed that the the url in the request to webservice is:

http://sample.domain.comhttp://sample.domain.com/path/path2

I tried multiple things f.e.

@RegisterRestClient(baseUri = "http://sample.domain.com/path/path2")

But the issue was still in place

The domain part id doubled for some reason. Anyone encountered similar issue?

Of course on my sample app everything works as expected. I'll let you know if I found the reason of it

Looking forward to it :)

For some reason, without any manual changes our application started using some proxy.

adding this to application.properties fixed the issue.

quarkus.rest-client."webservice-api".proxy-address=none

I figured it out by just going very deep in the debugger to find out that the url is not doubled by the url builder itself.
In some point of io.quarkus.rest.client.reactive.runtime.MicroProfileRestClientResponseFilter I found out in debugger that the requestContext.restClientRequestContext.uri is correct but in the logs it was doubled as described above.
