Object mapping for mapper name tried to parse field – How to solve this Elasticsearch exception

Opster Team

August-23, Version: 6.8-7.15

Briefly, this error occurs when Elasticsearch tries to parse a field that is not correctly mapped or the data type of the incoming field is different from the one defined in the mapping. To resolve this, you can either update the mapping to match the incoming data type or modify the incoming data to match the existing mapping. Also, ensure that the field name in the document matches the field name in the mapping. If the error persists, you may need to reindex your data with the correct mapping.

This guide will help you check for common problems that cause the log ” object mapping for [” + mapper.name() + “] tried to parse field [ ” to appear. To understand the issues related to this log, read the explanation below about the following Elasticsearch concepts: mapping, index.

 if (token.isValue()) {
 throw new MapperParsingException("object mapping for [" + mapper.name() + "] tried to parse field [" + currentFieldName
 + "] as object; but found a concrete value");
 }  if (mapper.isNested()) {
 context = nestedContext(context; (NestedObjectMapper) mapper);
