sharepoint rest api – Sortlist problem

I'm trying to run a query here and it does not seem to take into account the sortlist parameter.

https://mysite.sharepoint.com/site/_api/search/query?querytext='path:https://mysite.sharepoint.com/site/Pages'&sortlist='ViewsRecent: descending & # 39; & RowLimit = 15

It returns the records, but it is not sorted by ViewsRecent. If I have changed ViewsRecent to something else (for example, ViewsDDDRecent), I get the same results, so my query has no results.

The property seems to be sortable. ViewsRecent is of type Integer, Query = Query, Recover = Retrieve, Sort = Sort, and Safe = Safe. In addition, it does not appear that this allows us to change the other parameters of this property (for example, the search is grayed out). I'm not sure that affects everything.

Any help would be greatly appreciated.
