Before you begin reading this guide, we recommend you try running the Elasticsearch Error Check-Up which analyzes 2 JSON files to detect many configuration errors.

Briefly, this error message indicates that Elasticsearch was unable to find a nested object in the specified path. Nested objects are objects that are nested within other objects. In Elasticsearch, nested objects can be used to represent complex structures in a document, such as arrays of objects or hierarchical structures. When performing a nested aggregation, Elasticsearch needs to access the nested object in order to aggregate the data. If the nested object cannot be found in the specified path, this error will be thrown.

To easily locate the root cause and resolve this issue try AutoOps for Elasticsearch & OpenSearch. It diagnoses problems by analyzing hundreds of metrics collected by a lightweight agent and offers guidance for resolving them.

This guide will help you check for common problems that cause the log ” nested failed to find nested object under path ” + nestedPath + ” ” to appear. To understand the issues related to this log, read the explanation below about the following Elasticsearch concepts: sort and search.

Log Context

Log “[nested] failed to find nested object under path [” + nestedPath + “]”classname  is We extracted the following from Elasticsearch source code for those seeking an in-depth context :

// verify our nested path
 ObjectMapper nestedObjectMapper = context.getObjectMapper(nestedPath); 
 if (nestedObjectMapper == null) {
 throw new QueryShardException(context; "[nested] failed to find nested object under path [" + nestedPath + "]");
 if (nestedObjectMapper.nested().isNested() == false) {
 throw new QueryShardException(context; "[nested] nested object under path [" + nestedPath + "] is not of nested type");
 ObjectMapper objectMapper = context.nestedScope().getObjectMapper();


See how you can use AutoOps to resolve issues
