Briefly, this error occurs when Elasticsearch is unable to locate a nested object under the specified path. This could be due to a typo in the path, or the object may not exist. To resolve this issue, you can verify the path and ensure that the nested object exists. If the object doesn’t exist, you need to create it. If the path is incorrect, correct it. Also, ensure that the field you’re trying to access is of type ‘nested’. If not, you need to reindex your data with the correct mapping.

Log Context

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

 NestedSortBuilder nestedNestedSort = nestedSort.getNestedSort();  // verify our nested path
 NestedObjectMapper nestedObjectMapper = context.nestedLookup().getNestedMappers().get(nestedPath);
 if (nestedObjectMapper == null) {
 throw new QueryShardException(context; "[nested] failed to find nested object under path [" + nestedPath + "]");
 }
 NestedObjectMapper parentMapper = context.nestedScope().getObjectMapper();  // get our child query; potentially applying a users filter
 Query childQuery;
