Before you dig into reading this guide, have you tried asking OpsGPT what this log means? You’ll receive a customized analysis of your log.

Try OpsGPT now for step-by-step guidance and tailored insights into your Elasticsearch operation.

Briefly, this error occurs when the “_parent” field in an Elasticsearch document is not properly configured with a parent type. This is a requirement for parent-child relationships in Elasticsearch. To resolve this issue, you can either configure a parent type for the “_parent” field or remove the “_parent” field if it’s not necessary. Also, ensure that the parent type exists in your index mapping. If you’re using Elasticsearch 6.x or later, consider using the “join” field instead, as parent-child relationships are deprecated.
