我在 pom.xml 中使用了以下插件

但我收到以下错误。我无法解决该错误
由于阶段失败而中止作业：阶段 4.0 中的任务 0 失败 1 次，最近一次失败：阶段 4.0 中丢失任务 0.0（TID 4，本地主机，执行程序驱动程序）：java.lang.ClassCastException：org.apache.spark.sql。在 org.apache.spark.sql.geosparksql.expressions.ST_GeomFromWKT.eval 中，catalyst.util.GenericArrayData 无法转换为 org.apache.spark.unsafe.types.UTF8String
