安装的插件版本是 Version: 7.9.3.0

使用语句 SELECT * FROM kibana_sample_data_ecommerce

请求时返回
{"error":{"root_cause":[{"type":"x_content_parse_exception","reason":"[1:1] [sql/query] failed to parse object"}],"type":"x_content_parse_exception","reason":"[1:1] [sql/query] failed to parse object","caused_by":{"type":"json_parse_exception","reason":"Unrecognized token 'SELECT': was expecting (JSON String, Number, Array, Object or token 'null', 'true' or 'false')\n at [Source: (org.elasticsearch.common.bytes.AbstractBytesReference$MarkSupportingStreamInputWrapper); line: 1, column: 8]"}},"status":400}
