Briefly, this error occurs when the size setting for the shared cache in Elasticsearch is set to a negative value. Elasticsearch requires this value to be non-negative for proper functioning. To resolve this issue, you can adjust the shared cache size setting in your Elasticsearch configuration file (elasticsearch.yml) to a non-negative value. Alternatively, you can use the Elasticsearch API to update this setting dynamically, again ensuring the value is non-negative.
