Running `inspect` on a WASM bundle fails if the bundle contains an annotation with the `related_resources` metadata field

[dxh9845]

Short description

Running opa inspect on a built WASM bundle that has the following related_resources annotation:

package main

import data.meta.foo

# METADATA
# entrypoint: true
# related_resources:
#  - ref: https://google.com
#    description: Some description
zone_alias := foo

Will fail with the following message:

error: bundle bundle.tar.gz: bundle load failed on manifest decode: json: cannot unmarshal string into Go struct field RelatedResourceAnnotation.wasm.annotations.related_resources.ref of type url.URL

Steps To Reproduce

1. Clone the following repo: https://github.com/dxh9845/opa-broken-wasm-build-poc/tree/dherzig/broken-annotations

   git clone https://github.com/dxh9845/opa-broken-wasm-build-poc.git

2. Checkout the branch containing the broken behavior:

   git checkout dherzig/broken-annotations

3. Run make fail to build the bundle and see the failure:

   make fail

Expected behavior

OPA can inspect the built WASM bundle without an error.

Additional context

This works for OPA packages built for rego. However, the WASM implementation seemingly cannot handle

Thanks for reporting this 👍 I haven't looked into it, but it sounds somewhat related to #6529 ... at least in how they both relate to a different compilation mode messing with metadata annotations. Have you had a chance to look at the files in the bundle?

Here you go:

Bundle contents

manifest.json

{
    "revision": "",
    "roots": [
        "main",
        "meta",
        "some_data"
    ],
    "wasm": [
        {
            "entrypoint": "main/zone_alias",
            "module": "/policy.wasm",
            "annotations": [
                {
                    "entrypoint": true,
                    "related_resources": [
                        {
                            "description": "Some description",
                            "ref": "https://google.com"
                        }
                    ],
                    "scope": "rule"
                }
            ]
        },
        {
            "entrypoint": "meta/foo",
            "module": "/policy.wasm",
            "annotations": [
                {
                    "entrypoint": true,
                    "scope": "rule"
                }
            ]
        }
    ]
}

bundle/main.rego

package main

import data.main.zone_alias

import data.meta.foo

Ah, thanks! No, this looks like a different issue then, as the metadata annotation is in the manifest. And hopefully easier to resolve 🙂
