# X_SCRAPE_PDF_ROUTE_INVALID

## Means

a pdf() route is not a path on this app

## Typical cause

route() answered something other than a path beginning with one slash — a full URL, a protocol-relative //host path or a backslash — and the printing browser only ever loads the app own origin

## Fix

`return a path from route(): pdf({ route: ({ input }) => '/invoices/' + input.id + '/print' })`
