Error when trying to make a REST Call in Quarkus

Question

I'm trying to execute a request at another service that I own. The guides I'm using to create the app are:

I'm getting an error like:

org.jboss.resteasy.spi.UnhandledException: java.lang.RuntimeException: Error injecting com.easy.ecomm.core.product.ProductClient com.easy.ecomm.core.cart.CartService.productClient

org.eclipse.microprofile.rest.client.RestClientDefinitionException: Parameters and variables don't match on interface com.easy.ecomm.core.product.ProductClient::findProductById

Here's the class ProductClient

import org.eclipse.microprofile.rest.client.inject.RegisterRestClient;

@Path("products")
@RegisterRestClient(configKey = "products-api")
public interface ProductClient {

    @GET
    @Path("{id}")
    Product findProductById(String id);

}

Here's the Service Layer:

import org.eclipse.microprofile.rest.client.inject.RestClient;

import javax.enterprise.context.ApplicationScoped;
import javax.inject.Inject;

@ApplicationScoped
public class CartService {

    @Inject
    @RestClient
    ProductClient productClient;

    public void addItem(String cartId, String productId, Integer amount){
        // Code to find the cart on a queue.
        Product product = findProduct(productId);
        cart.getItems().add(new CartItem(amount, product));
    }

    private Product findProduct(String productId) {
        return productClient.findProductById(productId);
    }
}

and the application.properties:

products-api/mp-rest/url=http://localhost:8060
products-api/mp-rest/scope=javax.inject.Singleton

The dependencies are the same as we have on the guides quarkus-rest-client and quarkus-rest-client-jackson

Things that I've already tried:

Remove the ConfigKey from the @RegisterRestClient and use the full path on the application.properties, add the Jandex Plugin on my POM.xml as described here.

But still no success. Each change gives me the same error message.

Have you tried adding this pom dependency for a related error ? https://stackoverflow.com/questions/13629076/javax-inject-inject-does-not-work — duppydodah, Mar 03 '21 at 04:51
Are you missing the `@PathParam` annotation on the argument of `findProductById`? I.e. try `findProductById(@PathParam String id)` — Nikos Paraskevopoulos, Mar 03 '21 at 08:30
Yeah, @NikosParaskevopoulos you're right, I was missing the param. — Johnnes Souza, Mar 11 '21 at 04:13

You forgot to annotate your path variable with @PathParam, that's why it can't instantiate the client:

import org.eclipse.microprofile.rest.client.inject.RegisterRestClient;
import javax.ws.rs.PathParam;

@Path("products")
@RegisterRestClient(configKey = "products-api")
public interface ProductClient {

    @GET
    @Path("{id}")
    Product findProductById(@PathParam("id") String id);

}
