Describe the bug

On creating the warm index and or indexing docs, if we check the node stats, we get the failure response :

{ "error": { "root_cause": [{ "type": "illegal_argument_exception", "reason": "Values less than -1 bytes are not supported: -2084b" } ], "type": "illegal_argument_exception", "reason": "Values less than -1 bytes are not supported: -2084b", "suppressed": [{ "type": "illegal_state_exception", "reason": "Failed to close the XContentBuilder", "caused_by": { "type": "i_o_exception", "reason": "Unclosed object or array found" } } ] }, "status": 400 }

With stacktrace:

No response

To Reproduce

1. Create Warm Index
2. Index a doc
3. Check the node stats using API : _nodes/stats
4. We get the error response

Expected behavior

Node stats API should work even if search query not executed.
