Briefly, this error occurs when you try to set the “store” attribute to “true” for a field in Elasticsearch that doesn’t support this setting. Not all field types support the “store” attribute. To resolve this issue, you can either change the field type to one that supports the “store” attribute or remove the “store” attribute from the field’s mapping. Alternatively, you can use the “_source” field to retrieve the original data, which is a common practice in Elasticsearch and often negates the need for the “store” attribute.
