Spring Cloud Openfeign @PatchMapping and @DeleteMapping insert unwanted slash when using url and specific value

Replicate problem:

Pom relevant deps:

    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>2022.0.4</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-openfeign</artifactId>
        </dependency>
        <dependency>
            <groupId>io.github.openfeign</groupId>
            <artifactId>feign-hc5</artifactId> <!-- Required to use PATCH over default HttpURLConnection -->
        </dependency>

Config in application-local.properties

feign.url=https://subdomain.address.com/endpoint

Client:

@FeignClient(name = "test-client", url = "${feign.url}")
public interface TestClient {
    @PatchMapping(value = "('{id}')")
    void patchTest(@PathVariable String id, @RequestBody TestDto dto);

    @DeleteMapping(value = "('{id}')")
    void deleteTest(@PathVariable String id);
}

Expected behaviour is a call from client.patchTest(id, dto) results in a call to: https://subdomain.address.com/endpoint('id') Measured behaviour however is a call to: https://subdomain.address.com/endpoint/('id') introducing an additional slash and creating a bad request for both the PATCH and the DELETE, GET and POST do not exhibit this.

Desired behaviour is no magic slash.

Hello @MarcelTon , I've just tried it and I see the same behaviour for GET also. If you were able to replicate a different behaviour for GET, please provide your sample. Furthermore, this is not a Spring Cloud OpenFeign specific behaviour. The uriTemplate is being added by the feign.RequestTemplate#uri(java.lang.String, boolean) method in OF. I see you've created an issue there and they've requested you to move it here, but I'm not sure why; Furthermor, it seems to be done by design there, as OF expects to get complete path segments from the user, i.e., if you do sth like this with OF (without the Spring Cloud OF dependency in your project even):

@RequestLine("GET ('test')")
String getTest();

you will still end up with GET https://subdomain.address.com/endpoint/('test') being called, and we expect the same with Spring Cloud OF.
