Hi @janlukajerkovic-netizen,

The error shows something is trying to assign to a read-only protocol property in getManifestBaseUrl, but the stack trace only shows minified Metro bundler module numbers, so I can't tell what is actually causing this.

Could you help me out with:

1. Full unminified stack trace. Check your Metro bundler terminal output, it should show the actual file names
2. Is getManifestBaseUrl a method you wrote, or is it from a library you're using?

With the unminified trace, I can determine if this is related to Amplify or something else in your setup.

Thanks!
