Additional Information
When providing a serverGen value in the request, the service uses it as the starting generation to return all changes that have occurred since that point. In the response, the serverGen value reflects the latest generation of the layer at the time of extraction, not the input value. This design allows the use of the returned serverGen for subsequent incremental sync operations, ensuring they always have the most recent generation for future requests. Refer to the Extract Changes REST API documentation stating 'If a single value is provided, all changes that have happened since that generation are returned.': https://developers.arcgis.com/rest/services-reference/enterprise/extract-changes-feature-service/.Steps to Reproduce
