Capsule.toml component declares both `file` and…

Error message

Capsule.toml component declares both `file` and `entrypoint`; refusing an ambiguous executable path

What it means

Manifest-binding guard in bind_manifest_to_packaged_wasm: the [components] table in Capsule.toml declares both `file` and `entrypoint` for the single component, making the executable path ambiguous. Since the build packages exactly one cdylib whose path is known, the manifest must identify it via exactly one key; both present means a contradictory user edit and packaging aborts.

Solutions

1. Keep only `file` (preferred for packaged cdylibs) and delete `entrypoint`
2. Or keep only `entrypoint` if that is your intended layout
3. Rebuild after making the component path unambiguous
