Kibana : Error fetching users: An internal server error occurred

[pawarrchetan (Chetan Pawar)]

Hello Fellow Community users,
Since a week I am continuously encountering Internal Server Error while accessing any link from my Kibana Console.
We use Elastic Cloud subscription hosted on AWS.
Elastic Stack version 7.7

The exact error looks like -

{"statusCode":500,"error":"Internal Server Error","message":"[parent] Data too large, data for [<http_request>] would be [2055541368/1.9gb], which is larger than the limit of [2040109465/1.8gb], real usage: [2055541368/1.9gb], new bytes reserved: [0/0b], usages [request=328/328b, fielddata=117172/114.4kb, in_flight_requests=11271436/10.7mb, accounting=143134992/136.5mb]: [circuit_breaking_exception] [parent] Data too large, data for [<http_request>] would be [2055541368/1.9gb], which is larger than the limit of [2040109465/1.8gb], real usage: [2055541368/1.9gb], new bytes reserved: [0/0b], usages [request=328/328b, fielddata=117172/114.4kb, in_flight_requests=11271436/10.7mb, accounting=143134992/136.5mb], with { bytes_wanted=2055541368 & bytes_limit=2040109465 & durability=\"PERMANENT\" }"}

Can you please help me understand if I need any specific settings to overcome this error ?

A guess is that you are sending too much data other the network or you are asking for too much data.

Could you share the requests you are sending?

Hello @dadoonet
I am using any normal interface or link available in Kibana.
For example : User Management or Discover.

For example :
GET /_cat/indices?v&s=index
{ "error" : { "root_cause" : [ { "type" : "circuit_breaking_exception", "reason" : "[parent] Data too large, data for [<transport_request>] would be [2043959180/1.9gb], which is larger than the limit of [2040109465/1.8gb], real usage: [2043907656/1.9gb], new bytes reserved: [51524/50.3kb], usages [request=328/328b, fielddata=25824/25.2kb, in_flight_requests=208520/203.6kb, accounting=144173048/137.4mb]", "bytes_wanted" : 2043959180, "bytes_limit" : 2040109465, "durability" : "PERMANENT" } ], "type" : "circuit_breaking_exception", "reason" : "[parent] Data too large, data for [<transport_request>] would be [2043959180/1.9gb], which is larger than the limit of [2040109465/1.8gb], real usage: [2043907656/1.9gb], new bytes reserved: [51524/50.3kb], usages [request=328/328b, fielddata=25824/25.2kb, in_flight_requests=208520/203.6kb, accounting=144173048/137.4mb]", "bytes_wanted" : 2043959180, "bytes_limit" : 2040109465, "durability" : "PERMANENT" }, "status" : 429 }

So whatever you are doing, you get this error?
Could you try the same _cat command but using curl instead?
