and i don't think this error is caused by unnest, for example with this new plan ``` let plan = LogicalPlanBuilder::scan("t", Arc::new(DefaultTableSource::new(provider)), None)? .filter(binary_expr( col("column1"), datafusion_expr::Operator::Gt, lit(ScalarValue::new_utf8("some_val")), ))? // .unnest_column("arr_col")? .build()?; ``` It will throw the same error because datafusion cannot handle the type difference at execution time, meaning the table provider should correctly provide the type for column `column1` for type_coercion to happen (at plan time) -- This is an automated message from the Apache Git Service.
