We are trying to call \_nodes/stats API from our monitoring systems to monitor ES cluster & nodes and its throwing up the below error but \_nodes//stats works fine. Can anybody throw some light on why this is happening ?

ElasticSearch Version - "7.1.1"

curl -X GET -u elastic:XXX X.X.X.X:9200/\_nodes/stats

{"error":{"root\_cause":[{"type":"illegal\_argument\_exception","reason":"Values less than -1 bytes are not supported: -4b"}],"type":"illegal\_argument\_exception","reason":"Values less than -1 bytes are not supported: -4b","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}

Regards,  
Prem
