Briefly, this error occurs when you’re configuring Elasticsearch AWS settings and you specify both the ‘region’ and ‘endpoint’ parameters. These parameters are mutually exclusive, meaning you should only use one or the other. To resolve this issue, you can either remove the ‘region’ parameter if you want to use a specific ‘endpoint’, or remove the ‘endpoint’ parameter if you want to use a ‘region’. Make sure to save your changes and restart Elasticsearch for the changes to take effect.
