Assistance Needed with 413 Error in Kibana Dashboard

Hello Elasticsearch community,

I'm encountering a 413 error when working with a dashboard containing multiple panels in Kibana. I've attempted to resolve this by modifying the server.maxPayload setting. According to the documentation here, I changed the setting from the default 1048576 to 8388608.

Steps I followed:

  1. Updated the Kibana setting server.maxPayload to 8388608.
  2. Confirmed the setting by describing the Kibana resource, which shows my updated value.
  3. Noticed that the secret containing the full config displays the value in scientific notation: maxPayload: 8.388608e+06.

Despite these changes, the issue persists, and when I debug the POST request via the browser's developer tools, the request body is still truncated to 1048576 characters.

Additional environment details:

  • I'm using the ECK Operator version 2.15.0.
  • Elasticsearch and Kibana versions both are 8.15.1.

Could anyone suggest what I should investigate next to resolve this error? Are there other configurations or elements I might be overlooking?

Thank you for your assistance!
