jackwener opened a new issue, #5191:
URL: https://github.com/apache/arrow-datafusion/issues/5191

   **Describe the bug**
   When invoke nullable(), if plan is semi/anti join, all_schema() only just contain one side child output.
   If we want to compute expr, it will fail.
   like:
   ```sql
   t1 semi join t2 on t1.id = t2.id
   ```
   due to schema just is `[t1.id] (join), [t1.id](left) , [t2.id] (right)`.
   
   so  `t1.id = t2.id` can't invoke `nullable()`
