Export encountered errors on ${failedPages.length} ${failedP

Error message

Export encountered errors on ${failedPages.length} ${failedPages.length === 1 ? 'path' : 'paths'}:
	${failedPages.sort().join('\n\t')}

What it means

Final failure report in exportAppImpl: the export run collected failedExportAttemptsByPage entries — pages whose prerender/export attempts threw. It aggregates the failed pages, sorts them, and lists them (tab-indented) under this summary as the terminating error so the user sees exactly which paths did not export.
