Nested expressions were added to Substrait in https://github.com/substrait-io/substrait/pull/351 (part of release 0.36.0). When given a plan with a nested expression, the validator complains that nested is not one of the valid expression types (which is expected because the validator currently only supports release 0.20.0).
Fatal error:
Failed to parse relations field: Failed to parse input field: Failed to parse expressions field: Message type "substrait.Expression" has no field named "nested" at "Plan.relations[0].root.input.project.expressions[0]".
Available Fields(except extensions): "['literal', 'selection', 'scalarFunction', 'windowFunction', 'ifThen', 'switchExpression', 'singularOrList', 'multiOrList', 'cast', 'subquery', 'enum']"...
