Getting search_phase_execution_exception in Kibana Discover pane

[ankitdevnalkar]

I have many indices such as cloud-audit-aws, cloud-audit-azure, cloud-audit-gsuite, cloud-audit-secret-tools, cloud-audit-github, and many more starting with cloud-audit. I have created an index pattern cloud-audit* to merge all indices data to create a few visualizations.

After creating index pattern, while checking all events from discover pane it gives me the below error. Can anyone help me understand what is wrong here?

I tried following this thread and disabled Highlight Results option but no success.

Can anyone help? We are facing this issue in the production environment.

PUT .apm-agent-configuration/_settings
{
  "index.max_docvalue_fields_search": 300
}
