E.g.
java.lang.IllegalStateException: com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "description" (class io.substrait.extension.ImmutableSimpleExtension$Type$Json), not marked as ignorable (3 known properties: "urn", "name", "structure"])
at [Source: (StringReader); line: 8, column: 1] (through reference chain: io.substrait.extension.ImmutableSimpleExtension$ExtensionSignatures$Json["types"]->java.util.ArrayList[0]->io.substrait.extension.ImmutableSimpleExtension$Type$Json["description"])
There may be more valid things that aren't accounted for.
