Error message

canceled

What it means

Thrown by ElectronFileProvider.selectAndStoreFile when the native open dialog returns `canceled: true` or an empty `filePaths` array. The lower-cased 'canceled' is the canonical signal that the user dismissed the picker, used so callers can pattern-match on it.

Solutions

1. Catch the error in the caller and treat 'canceled' as a benign user abort (no toast, just stop the flow).
2. If mocking in tests, stub `electron.dialog.showOpenDialog` to resolve with a chosen filePaths array.
3. Pre-validate that a file path is expected before opening the dialog to reduce accidental cancels.
4. Differentiate from real errors by matching `e.message === 'canceled'` rather than generic catch.

Example fix

// before
if (result.canceled || !result.filePaths.length) throw new Error('canceled')

// caller pattern
try { key = await fileProvider.selectAndStoreFile('Private key') }
catch (e) { if (e.message === 'canceled') return; throw e }

try {
    key = await electronProvider.selectAndStoreFile('Select file')
} catch (e) {
    if (e instanceof Error && e.message === 'canceled') return  // user dismissed dialog
    throw e
}

When it happens

Trigger: Calling `selectAndStoreFile` in an Electron host; the user clicks Cancel, presses ESC, or closes the `dialog.showOpenDialog` window. Also thrown if the dialog returns no paths for any reason (rare platform bug).

Common situations: User cancels while selecting a private key, color scheme file, or other importable asset; an automated test invokes the provider without mocking the dialog and it returns canceled.
