Kibana Dev Tools Console does not execute full _bulk request

Elastic Stack Kibana
1

Description: When running a valid Elasticsearch Bulk API request in Kibana Dev Tools Console, the console does not appear to process all NDJSON operations as a single request. Example: POST /logs/_bulk {"create":{}} {"@timestamp":"2026-07-24T11:01:00Z","message":"Health check passed","log.level":"INFO","service.name":"api-gateway"} {"create":{}} {"@timestamp":"2026-07-24T11:01:05Z","message":"Disk usage at 95 percent","log.level":"ERROR","service.name":"monitoring"} Actual result: HTTP 400 Validation Failed: 1: no requests added; Expected result: Both documents should be indexed successfully by the Bulk API. Steps to reproduce: 1. Open Kibana 2. Go to Dev Tools > Console 3. Paste the Bulk API request above 4. Run the complete request 5. Observe the 400 error Additional information: The issue continues after adding a trailing newline and running the complete request.

Hello @Abdullah_Hamza

Welcome to the community.

What is the ELK version ?

When trying this in 9.4.x version, it works :

POST /logs/_bulk
{"create":{}} {"@timestamp":"2026-07-24T11:01:00Z","message":"Health check passed","log.level":"INFO","service.name":"api-gateway"}
{"create":{}} {"@timestamp":"2026-07-24T11:01:05Z","message":"Disk usage at 95 percent","log.level":"ERROR","service.name":"monitoring"}

Output :

{
  "errors": false,
  "took": 400,
  "items": [
    {
      "create": {
        "_index": "logs",
        "_id": "7eoDeqABHnXAfMBeDCRb",
        "_version": 1,
        "result": "created",
        "_shards": {
          "total": 2,
          "successful": 1,
          "failed": 0
        },
        "_seq_no": 0,
        "_primary_term": 1,
        "status": 201
      }
    },
    {
      "create": {
        "_index": "logs",
        "_id": "7uoDeqABHnXAfMBeDCRb",
        "_version": 1,
        "result": "created",
        "_shards": {
          "total": 2,
          "successful": 1,
          "failed": 0
        },
        "_seq_no": 1,
        "_primary_term": 1,
        "status": 201
      }
    }
  ]
}

Both the records were added :

GET logs/_count

{
  "count": 2,
  "_shards": {
    "total": 1,
    "successful": 1,
    "skipped": 0,
    "failed": 0
  }
}
