PdfAdapter does not support importing slices from PDF.

Error message

PdfAdapter does not support importing slices from PDF.

What it means

toSliceSnapshot on PdfAdapter is an intentionally unimplemented adapter method: PDF exports cannot be turned into slice snapshots, so any attempt to import a slice from a PDF hits this hard rejection. It fires when a caller passes a ToSliceSnapshotPayload<PdfAdapterFile> to this adapter.

Solutions

1. Slice-level PDF import is not supported. Import the content at block or doc level using another adapter, or extract the PDF content externally first.
2. Add a capability check before calling toSliceSnapshot on PdfAdapter and gracefully degrade to a 'not supported' notification.

Example fix

try {
  await pdfAdapter.toSliceSnapshot(payload);
} catch {
  // PDF slice import unsupported — extract content with pdf.js instead
  const text = await extractPdfText(file);
  return markdownAdapter.toSliceSnapshot({ file: text, assets, workspaceId, pageId });
}
