Table structure and query statements?
CREATE TABLE IF NOT EXISTS dwd_content_detail ( id varchar(80), feature_embedding array<array< FLOAT >> ) UNIQUE KEY(id) DISTRIBUTED BY HASH(id) BUCKETS 10 PROPERTIES ( "replication_allocation" = "tag.location.default: 1", "enable_unique_key_merge_on_write" = "true", "light_schema_change" = "true", "store_row_column" = "true", "compression"="zstd" );
SELECT id,feature_embedding,lag(feature_embedding,1,null) over (partition by id) as feature_embedding_lag FROM dwd_content_detail

What's Wrong?
表dwd_content_detail中存在字段:feature_embedding ARRAY<ARRAY< FLOAT >>,且部分记录中该字段值为空,然后当执行sql( SELECT id,feature_embedding,lag(feature_embedding,1,null) over (partition by id) as feature_embedding_lag FROM dwd_content_detail)时会报错: org.jkiss.dbeaver.model.sql.DBSQLException: SQL 错误 [1105] [HY000]: errCode = 2, detailMessage = No matching function with signature: lag(ARRAY, BIGINT, NULL_TYPE).

What You Expected?
execute normally
How to Reproduce?
execute sql: SELECT id,feature_embedding,lag(feature_embedding,1,null) over (partition by id) as feature_embedding_lag FROM dwd_content_detail
