We upgraded to
dask 2024.2.1
dask-expr 0.5.3
pandas 2.2.0
Python 3.10.9
But we getting error while trying to run with dask.config.set({‘dataframe.query-planning’: True})
No issue if ({‘dataframe.query-planning’: False}
```auto

dask.config.set({"dataframe.convert-string": True})

Hi @slepeturin, welcome to Dask community!
Would you be able to provide a minimum reproducer raising this error? At least some code snippet.
As query planning with `dask-expr` is a recent feature, you are also encourage to [give feedback on github](https://github.com/dask/dask/issues/10995), or even open a new issue, but here it still lacks a bit of context I think.

Hi @[guillaumeeb](https://dask.discourse.group/u/guillaumeeb),
Thank you for the reply. .
We are planning the upgrade to the latest Dask version 2024.3.0 .
Maybe it would solve the issue.
Thank you,
Steve
