If you are using an Elasticsearch database older than 7.17.29, you need to upgrade it. Download the 7.17.29 version and install it using the same steps as before. In services, stop the Elasticsearch 7.17.29 version. Then, move the data folder from your older version (for example, c:\elasticsearch\elasticsearch-7.10.2\data) to the new version (c:\elasticsearch\data) and start the service.
Afterwards, you need to restart the Tomcat just in case.
