Upsert is throwing DocumentMissingException

I am using Spring Boot and ElasticSearch. When I am trying to upsert using Spring, it is throwing DocumentMissingException when there is no document present in the ElasticSearch. The same code works fine when there is a document present in the ElasticSearch.

Exception Stacktrace: Bulk indexing has failures. Use ElasticsearchException.getFailedDocuments() for detailed messages [{U65929AR1978SGC001748=[company/vteSxfKoRF-k4g982vissw][[company][2]] DocumentMissingException[[_doc][U65929AR1978SGC001748]: document missing], U45309AR2000PTC006288=[company/vteSxfKoRF-k4g982vissw][[company][3]] DocumentMissingException[[_doc][U45309AR2000PTC006288]: document missing],...


public <S extends Company> void saveAllCustom(Iterable<S> companies) {

	List<UpdateQuery> updateQueries = new ArrayList<UpdateQuery>();

	ObjectMapper oMapper = new ObjectMapper();
	for (S company : companies) {

		Map<String, Object> companyJsonMap = (Map<String, Object>) oMapper.convertValue(company, Map.class);
		Map<String, Object> paramsDocument = new HashMap<String, Object>();
		paramsDocument.put("doc", companyJsonMap);
		Script script = new Script(
				, "painless"
				, "if (ctx._source.dataAsOf < params.doc.dataAsOf) {ctx._source = params.doc}"
				, paramsDocument);
		UpdateRequest updateRequest = new UpdateRequest()
				.script(script) // Conditional Update

		UpdateQuery updateQuery = new UpdateQueryBuilder()

But a similar upsert command is working using CURL:

curl -X POST "localhost:9200/company/_doc/10001/_update" -H 'Content-Type: application/json' -d'
    "script": {
        "lang": "painless",
        "source": "ctx._source = params.doc",
        "params": {
            "doc": {
                "name": "XYZ LIMITED - updated",
                "cin": "10001"
    "upsert" : {
        "name": "XYZ LIMITED - newly created",
        "cin": "10001"

As per my understanding, when there is no document present in the ElasticSearch, it shouldn't throw a DocumentMissingException because I have added upsert(...) as well in the query.
