# X_SCRAPE_OUTPUT_INVALID

## Means

the extracted rows do not match the extract schema

## Typical cause

**terminal.** The selectors still match and what they yield no longer parses — a column that became empty, a number that became a range, a date that changed format

## Fix

align the extract schema with the page — the run's `page.html` artifact holds the markup the rows came from
