found multiple matching assets for key: %q

Error message

found multiple matching assets for key: %q

What it means

AssetStore.Find resolved the key to more than one asset (multiple asset paths matched the key/assetPath pair); the store expects a unique resolution and refuses to pick arbitrarily.

Solutions

1. Provide a more specific assetPath so only one asset matches
