Briefly, this error occurs when an upsert operation is attempted in Elasticsearch using a script that doesn’t perform any changes. Upsert operations are used to update existing documents or insert new ones if they don’t exist. If the script doesn’t make any changes, Elasticsearch considers it invalid. To resolve this issue, ensure that your script performs some form of modification to the document. This could be updating a field value, adding a new field, or even deleting a field. Also, check that the script is correctly formatted and doesn’t contain any syntax errors.

We extracted the following from Elasticsearch source code for those seeking an in-depth context :

    Tuple> executeScriptedUpsert(Script script; UpsertCtxMap ctxMap) {
        ctxMap = executeScript(script; ctxMap);
        UpdateOpType operation = UpdateOpType.lenientFromString(ctxMap.getMetadata().getOp(); logger; script.getIdOrCode());
        if (operation != UpdateOpType.CREATE && operation != UpdateOpType.NONE) {
            // Only valid options for an upsert script are "create" (the default) or "none"; meaning abort upsert
            logger.warn("Invalid upsert operation [{}] for script [{}]; doing nothing..."; operation; script.getIdOrCode());
            operation = UpdateOpType.NONE;

        return new Tuple(operation; ctxMap.getSource());
