Hi @bnamantis,

Maybe you could try to disable the use PyArrow String:

```auto
import dask 
dask.config.set({"dataframe.convert-string": False})

```

Hope you can see screenshot, same error, no change, I am running same example in the documentation, not sure if there is any versioning issue, are you able to run it without error?

Could you also provide the environment you are using, especially Pandas and Dask versions?

So I was able to reproduce you issue with Dask and dask-sql latest version.

But adding

```auto
import dask 
dask.config.set({"dataframe.convert-string": False})

```

Before any other thing in my code solved it.

An issue is already opened here: [[QST] NotImplementedError: The python type string is not implemented (yet) · Issue #1225 · dask-contrib/dask-sql · GitHub](https://github.com/dask-contrib/dask-sql/issues/1225).
