Expected a single zip file for notion import

Error message

Expected a single zip file for notion import

What it means

An input-count guard in the Notion import dialog: the fileOptions for Notion declare a single Zip file (multiple: false), and the importFunction requires exactly one selected file. It fires when files.length is not 1 (zero or multiple files reached the importer), which normally indicates the file picker options were bypassed or misconfigured.

Solutions

1. Select exactly one zip file exported from Notion.
2. Re-pick the file in the import dialog.

When it happens

Trigger: Thrown by the Notion import function when files.length is not exactly one, since Notion import requires a single exported zip archive.

Common situations: The Notion import was started without choosing exactly one zip export. Export the workspace from Notion as a zip and select that single file.
