Request URL: http://localhost:3000/api/v1/annotation/tasks/1883/finish
Request Method: POST
Payload: {annotation_user_for_failed_pages: "auto", validation_user_for_reannotated_pages: "auto"}
Status Code: 400 Bad Request
{"detail":"Validator did not mark any pages as failed, thus annotation_user_for_failed_pages param should be null."}

Back-end

• Don't accept edited pages and (invalid or valid) state in same revision
• Change algorithm to get latest revision

Algorithm to get latest revision:
For each revision from oldest to newest we need to fill lists with annotated, validated, failed using next logic:

• If in newest revision page in different state (from previous one), remove this page from previous list and add to new list
• In final revision must be not intersected lists with all pages from previous revisions and with latest state for each

Front-end

• Don't send pages edited and (invalid or valid) state in same revision
• Don't send field pages if no pages edited
