使用snowpark java API访问雪花：合并函数给出错误对象'SNOWPARK_TEMP_TABLE_' 不存在或未授权

我正在尝试使用 ACCOUNTADMIN 访问权限的 Snowpark API 连接到 Snowflake，当我尝试合并时出现以下错误。我做错了什么吗？

Updatable dfFull = session.table("RATINGS");
Updatable df = session.table("RATINGS_MOVIE_328");
..
RATINGS_MOVIE_328 table is subset of RATINGS table whose movieid is 328
..
 MergeBuilder mb = dfFull.merge(updatedDf,dfFull.col("USERID").equal_to(updatedDf.col("USERID")));
        Map<String, Column> assignments = new HashMap<>();
        assignments.put("RATING", updatedDf.col("RATING"));

..
MergeResult mr = mb.whenMatched().updateColumn(assignments).collect();

我遇到以下错误。任何指导都会有很大帮助。

合并到评级使用 ( SELECT "USERID" AS "r_J1pF_USERID", "MOVIEID" AS "r_J1pF_MOVIEID", "RATING" AS "r_J1pF_RATING", "TIMESTAMP" AS "r_J1pF_TIMESTAMP" FROM ( SELECT "USERID", "MOVIEID", to_decimal( "RATING", 38, 4) AS "RATING", "TIMESTAMP" FROM ( SELECT * FROM (SNOWPARK_TEMP_TABLE_GUYM0ZTBCG2K2R7)))) ON ("USERID" = "r_J1pF_USERID") 匹配时更新设置 "RATING" = "r_J1pF_RATING" net . Snowflake.client.jdbc.SnowflakeSQLException：SQL编译错误：对象“SNOWPARK_TEMP_TABLE_GUYM0ZTBCG2K2R7”不存在或未授权。
