# 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. Files modified: - packages/twenty-server/src/engine/api/rest/input-request-parsers/rest-input-request-parser.exception.ts - packages/twenty-server/src/engine/api/rest/input-request-parsers/starting-after-parser-utils/parse-starting-after-rest-request.util.ts - 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. Files modified: - packages/twenty-server/src/engine/api/common/common-args-processors/data-arg-processor/validator-utils/validate-rating-and-select-field-or-throw.util.ts - Test file Example error: Invalid value "BAD_VALUE" for field "stage". Valid values are: NEW, SCREENING, MEETING, PROPOSAL, CUSTOMER --- ### Testing - Added 5 new test cases for `parse-starting-after-rest-request.util.ts` - Added 6 new test cases for `parse-ending-before-rest-request.util.ts` - Added 1 new test case for `validate-rating-and-select-field-or-throw.util.ts` - All 21 tests passing --- Breaking Changes None - correct usage is unaffected. --------- Co-authored-by: Etienne <45695613+etiennejouan@users.noreply.github.com>
