case ArrayType(ArrayType(_, _), _) | ArrayType(StringType, _) =>

This line of code indicates that ArrayType(StringType, _) will be encoded to FeatureList, however, method encodeFeatureList does not handle this case, and will throw exception.

case _ => throw new RuntimeException(s"Cannot convert row element ${row.get(index)} to FeatureList.")

Is this on purpose or a bug?

Hello, any news regarding this ?

I have same issue. The documentation is also lying about this because it says that ArrayType(SringType) is supported.
