AbortError

Error message

Import cancelled

What it means

commitNativeImport checks the caller-supplied AbortSignal before starting; if the signal is already aborted the import is cancelled upfront by throwing a DOMException('Import cancelled', 'AbortError') instead of creating a session.

Solutions

1. No action needed; the user cancelled the import dialog.
2. Re-open the import dialog to start a new import.

When it happens

Trigger: Thrown as an AbortError DOMException in commitNativeImport when the provided AbortSignal is aborted, either before starting or between import batches.

Common situations: Expected when the user cancels an in-progress desktop import or the dialog closes. It is a normal cancellation path, not a failure.
