PanacheRepositoryResource fails on POST when the resource's path includes a @PathParam

[CYBERSHOU]

Describe the bug

I'm using the PanacheRepositoryResource interface to create the Jax Resources.
The only difference from what works is the use of a path parameter, like "/project/{projectId}/".

All my POST requests end up with 500 errors saying "Failed to add an entity" and further down the stacktrace it says
"Discovery failed for method com.envisage.gene.rest.project.dependent.TargetResourceJaxRs_597046d94bad44a89428c15444fc02a72e8750c2.get: RESTEASY012060: Not enough URI parameters: expecting 2 but only found 1".

Bearing in mind that the endpoint I'm trying to hit is something like:
http://localhost:8080/api/project/{projectId}/target

After a lot of tinkering around, I can only assume the error must be something with Panache itself.
Unless I have missed something.

Expected behavior

• A POST request is made to the endpoint: http://localhost:8080/api/project/{projectId}/target

• The server handles the request and creates the requested entity.

• A response with status 201 is returned.

Actual behavior

• A POST request is made to the endpoint: http://localhost:8080/api/project/{projectId}/target

• The server is unable to hit the endpoint and returns a 500 status error.

This error seems to be related to the generation of the links. As a workaround, you can try with disabling hal:

@ResourceProperties(hal = false)
public interface CollectionsResource extends PanacheRepositoryResource<CollectionsRepository, Collection, String> {
}

About the issue, can you share your resource class to reproduce and better troubleshoot what the root cause is? Thanks!

Thank you, but the issue remains. My ugly workaround right now is extending the path of the endpoint with "/add" by using a default method.

Yes! I will add an example.

Here is a entity I created to test the issue.

import jakarta.persistence.Entity;
import jakarta.persistence.GeneratedValue;
import jakarta.persistence.GenerationType;
import jakarta.persistence.Id;
import jakarta.persistence.SequenceGenerator;

@Entity
public class Test {

    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "test_seq")
    @SequenceGenerator(name = "test_seq", sequenceName = "test_sequence")
    private Long id;

    private String description;

    public Test() {}

    public Test(String description) {
        this.description = description;
    }

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }
}

The entity's repository is the standard:

import io.quarkus.hibernate.orm.panache.PanacheRepository;
import jakarta.enterprise.context.ApplicationScoped;

@ApplicationScoped
public class TestRepository implements PanacheRepository<Test> {
}

And the resource:

import io.quarkus.hibernate.orm.rest.data.panache.PanacheRepositoryResource;
import io.quarkus.rest.data.panache.ResourceProperties;

@ResourceProperties(hal = false, path = "api/project/{projectId}/test")
public interface TestResource extends PanacheRepositoryResource<TestRepository, Test, Long> {
}

I was able to reproduce the issue with this.

So, you're trying to use it as a sub-resource of a top parent resource. There is an existing feature request to support this use case: #28450
Closing as duplicated.

About disabling HAL, this was actually a bug that should be fixed in #35181. So, after merging this pull request, your issue will be gone.
