Briefly, this error occurs when you try to use the `collapse` feature in a scroll context in Elasticsearch. The `collapse` feature is used to collapse search results based on a certain field, while scroll is used for retrieving large numbers of results. Elasticsearch does not support using these two features together. To resolve this issue, you can either remove the `collapse` feature from your query or stop using scroll and paginate your results instead. Alternatively, you could perform the collapsing operation in your application code after retrieving the results.
