Topic: wrpc/rpc - authentication failed

I use wasmCloud with the following wit for one of my components:

package pipestack:customer@0.1.0;

interface customer {
    use wrpc:rpc/error@0.1.0.{error};
    run: func(input: string) -> result<string, error>;
}

world component {
    import wasi:config/runtime@0.2.0-draft;

    export customer;
}

When I try to build the component with wash build, I see the following error in the logs:

DEBUG oci_client::client: Failed to authenticate for image 'Reference { registry: "ghcr.io", mirror_registry: None, repository: "bytecodealliance/wasm-pkg/wrpc/rpc", tag: Some("latest"), digest: None }': {"errors":[{"code":"DENIED","message":"requested access to the resource is denied"}]}

Does anyone have an idea why this happens? I'll keep digging and report back if/when I find the solution.

While there is quite a bit of overlap, you might get better support in the wasmcloud slack: https://slack.wasmcloud.com/

Thank you, I started my troubleshooting journey over there :blush:. I'll make sure to update Slack and here when I find a resolution in case anyone else finds this through search.

Fixed it! I added the following to wasmcloud.toml

[registry.pull]
sources = [{ target = "wrpc:rpc", source = "https://github.com/wrpc/rpc/archive/v0.1.0.tar.gz" }]
