Common issues

This page contains a list of common issues and workarounds.

OpenSearch Dashboards fails to start

If you encounter the error FATAL Error: Request Timeout after 30000ms during startup, try running OpenSearch Dashboards on a more powerful machine. We recommend four CPU cores and 8 GB of RAM.

Requests to OpenSearch Dashboards fail with “Request must contain a osd-xsrf header”

If you run legacy Kibana OSS scripts against OpenSearch Dashboards—for example, curl commands that import saved objects from a file—they might fail with the following error:

{"status": 400, "body": "Request must contain a osd-xsrf header."}

In this case, your scripts likely include the "kbn-xsrf: true" header. Switch it to the osd-xsrf: true header:

curl -XPOST -u 'admin:<custom-admin-password>' 'https://DASHBOARDS_ENDPOINT/api/saved_objects/_import' -H 'osd-xsrf:true' --form file=@export.ndjson

Multi-tenancy issues in OpenSearch Dashboards

If you’re testing multiple users in OpenSearch Dashboards and encounter unexpected changes in tenant, use Google Chrome in an Incognito window or Firefox in a Private window.

Expired certificates

If your certificates have expired, you might receive the following error or something similar:

ERROR org.opensearch.security.ssl.transport.SecuritySSLNettyTransport - Exception during establishing a SSL connection: javax.net.ssl.SSLHandshakeException: PKIX path validation failed: java.security.cert.CertPathValidatorException: validity check failed
Caused by: java.security.cert.CertificateExpiredException: NotAfter: Thu Sep 16 11:27:55 PDT 2021

To check the expiration date for a certificate, run this command:

openssl x509 -enddate -noout -in <certificate>

Encryption at rest

The operating system for each OpenSearch node handles encryption of data at rest. To enable encryption at rest in most Linux distributions, use the cryptsetup command:

cryptsetup luksFormat --key-file <key> <partition>

For full documentation about the command, see cryptsetup(8) — Linux manual page.

Can’t update by script when FLS, DLS, or field masking is active

The Security plugin blocks the update by script operation (POST <index>/_update/<id>) when field-level security, document-level security, or field masking are active. You can still update documents using the standard index operation (PUT <index>/_doc/<id>).

Illegal reflective access operation in logs

This is a known issue with Performance Analyzer that shouldn’t affect functionality.
