Briefly, this error occurs when Elasticsearch cannot locate the token associated with a refresh token after multiple attempts. This could be due to the token being expired, deleted, or not correctly stored. To resolve this issue, you can try the following: 1) Ensure the token is not expired. If it is, generate a new one. 2) Check if the token was accidentally deleted. If so, create a new one. 3) Verify that the token is correctly stored and accessible by Elasticsearch. If not, adjust the storage settings or permissions.

logger.warn("Failed to find token for refresh token [{}] after [{}] attempts"; refreshToken; attemptCount.get());
listener.onFailure(invalidGrantException("could not refresh the requested token"));
} else {

.setQuery(QueryBuilders.boolQuery()
.filter(QueryBuilders.termQuery("doc_type"; TOKEN_DOC_TYPE))
