 - Fixed cluster API schemas ([#754](https://github.com/opensearch-project/opensearch-api-specification/pull/754))
 - Fixed schema validation for invalid properties in `retry` configuration ([#758](https://github.com/opensearch-project/opensearch-api-specification/pull/758))
 - Fixed nodes API schemas ([#761](https://github.com/opensearch-project/opensearch-api-specification/pull/761))
+- Fixed ingest API schemas ([#766](https://github.com/opensearch-project/opensearch-api-specification/pull/766))
 
 ### Changed
 - Changed `tasks._common:TaskInfo` and `tasks._common:TaskGroup` to be composed of a `tasks._common:TaskInfoBase` ([#683](https://github.com/opensearch-project/opensearch-api-specification/pull/683))
