### Problem Description

In 8.5, _nodes/stats returns a failure message if the node has closed indices. In previous versions, it works.
Please see steps to reproduce.

### Steps to Reproduce

```
$ curl -XPUT http://localhost:9200/test_index
$ curl http://localhost:9200/_nodes/stats  # <- it works
$ curl -XPOST http://localhost:9200/test_index/_close
$ curl http://localhost:9200/_nodes/stats
