To resolve this issue, you can either create a new index with the desired mapping or reindex the existing data into a new index with the updated mapping. Alternatively, you can use the ‘put mapping’ API to add new fields to the existing mapping, but remember that existing fields cannot be updated or removed.

 } else if (subobjects != mergeWith.subobjects) {
 throw new MapperException("the [subobjects] parameter can't be updated for the object mapping [" + name() + "]");
 }
 }  MapperBuilderContext objectBuilderContext = createChildContext(parentBuilderContext; simpleName());
 Map mergedMappers = null;
