I'm currently working on the
[function](https://github.com/apache/beam/pull/16911/files#diff-b497391b74a7130be5217a2d4ede920fe66059444bc248a6710ad9b6361ac2b3R81)
that converts the input, I noticed the error might be occurring because
[this](https://github.com/apache/beam/pull/16911/files#diff-b497391b74a7130be5217a2d4ede920fe66059444bc248a6710ad9b6361ac2b3R104)
```projects``` parameter doesn't have all the ```RexNode``` objects that it
needs.
I took a look at the ```AggregateScanConverter``` implementation of this
[input
conversion](https://github.com/apache/beam/blob/4dddaf9c3d70b5b858c16265abee4cdbf0c72631/sdks/java/extensions/sql/zetasql/src/main/java/org/apache/beam/sdk/extensions/sql/zetasql/translation/AggregateScanConverter.java#L121)
and it seems that it adds ```groupByList``` and ```aggregateList``` from the
zetaNode as ```RexNodes``` to the ```LogicalProject``` as ```projects``` and
```fieldNames```. I'm not sure how to make a similiar procedure for the
```AnalyticScan```, given that it doesn't have either a ```groupByList``` or an
```aggregateList```.
My question here is, what is the logic or purpose of converting and adding
these lists (```projects``` and ```fieldNames```) to a ```LogicalProject```?
