Asset does not exist: ${file}

Error message

Asset does not exist: ${file}

What it means

Runtime guard inside read() from $app/server: after stripping the assets prefix and decoding, the requested file key is not present in the generated manifest's server_assets map, meaning the asset was never recorded as a server-readable asset during build. Typically happens when the imported path doesn't match a built asset (wrong import, stale build, or asset excluded from the manifest).

Solutions

1. Import the asset by its module path and pass the resulting URL to read(), rather than hand-writing a path
2. Rebuild the app so the manifest's server_assets entries are regenerated
3. Check for typos or hash mismatches in the asset path
