repack Warning: ChunkLoadError: Loading chunk (chunkname) failed.

Describe the bug

Hi all. I am trying to follow the Re.Pack guides and take the 'local-chunks' example project and make it so that AsyncBody can be loaded from a CDN server.

To accomplish this, I have created a new Re.Pack 5 project. All packages install appropriately, pods install, etc. When I build the release bundle for iOS, it builds async_body.chunk.bundle and places it in the build outputs folder. All as expected.

What I'm confused on is this: I upload the chunk bundle to my CDN storage and provide the base URL in my resolver. The URL that should be generated is accurate, and if I plug it into my browser, I see the text representation of the chunk bundle. However, when I run the app, I get the following unhelpful error:

Without any other additional information I'm not sure what to do here. The issue reproduces on iOS and Android.

If it helps, the URL for the chunk bundle is here: https://pub-c0b0ae684e604a9eb8d0d0e57bd14a4c.r2.dev/async_body.chunk.bundle

Is anything else supposed to be uploaded to the CDN server? Am I misconfiguring something locally? When I have the app point to local, it loads fine (although it's loading the local tsx instead of a bundle, which I think is expected).

Any help is appreciated- thank you!
