Summary: After upgrading to Spark 3.4.1 we receive RuntimeException "is not valid external type"
Key: SPARK-45644
URL: https://issues.apache.org/jira/browse/SPARK-45644
Project: Spark
Issue Type: Question
Components: Spark Core
Affects Versions: 3.5.0, 3.4.1
Reporter: Adi Wehrli
A Spark job ran successfully with Spark 3.2.x and 3.3.x.
But after upgrading to 3.4.1 (as well as with 3.5.0) the following always occurs now:
{code}
scala.Some is not a valid external type for schema of array<string>
{code}
The corresponding stacktrace is:
