[GitHub] [arrow-datafusion] andygrove opened a new issue, #2907: Optimization rules create invalid projections
andygrove opened a new issue, #2907:
URL: https://github.com/apache/arrow-datafusion/issues/2907
**Describe the bug**
I am trying to run some complex SQL and am seeing errors such as:
```
thread 'q11' panicked at 'index out of bounds: the len is 12 but the index is 12', /home/andy/.cargo/git/checkouts/arrow-datafusion-71ae82d9dec9a01c/9401d6d/datafusion/optimizer/src/projection_push_down.rs:159:39
```
With the changes in https://github.com/apache/arrow-datafusion/pull/2900 I see a slighter more informative error:
```
FAILURE: Plan("Projection has mismatch between number of expressions (12) and number of fields in schema (42)")
```
**To Reproduce**
I do not have a repro to share currently. I am in the process of debugging this.
**Expected behavior**
Should not fail. Rules should avoid changing plans if there are errors rather than panic.
**Additional context**
None
