# Summary
(fixes#20044)
This PR implements two fixes for the REST API to enforce stricter
validation and provide better error messages.
Issue 1: Cursor parameter silently ignored
Problem: When users provided common cursor aliases (e.g., cursor, after,
before) instead of the correct parameter names (starting_after,
ending_before), the API silently ignored them and returned page 1 on
every request.
Solution: Added strict validation to detect common cursor aliases and
throw a clear error directing users to use the correct parameter names.

-
packages/twenty-server/src/engine/api/rest/input-request-parsers/ending-before-parser-utils/parse-ending-before-rest-request.util.ts
- Test files for both parsers
Example error:
Invalid cursor parameter 'cursor'. Use 'starting_after' for pagination.

Issue 2: OpportunityStageEnum not validated on REST
Problem: When creating or updating opportunities via REST with an
invalid stage value, the API either silently dropped the value or
returned a generic error without listing valid options.
Solution: Updated the SELECT field validation to include valid options
in the error message.

SCREENING, MEETING, PROPOSAL, CUSTOMER
