Hello everyone, I am unable to understand the issue with prefect-dask library(v0.2.6) and prefect v2.20.7. I end up with this error:

Traceback (most recent call last):

File "<string>", line 1, in <module>

File "/usr/local/lib/python3.10/site-packages/prefect_dask/__init__.py", line 2, in <module>

from .task_runners import DaskTaskRunner  # noqa

File "/usr/local/lib/python3.10/site-packages/prefect_dask/task_runners.py", line 89, in <module>

class DaskTaskRunner(BaseTaskRunner):

File "/usr/local/lib/python3.10/site-packages/prefect_dask/task_runners.py", line 256, in DaskTaskRunner

call: Callable[..., Awaitable[State[R]]],

TypeError: 'ModelMetaclass' object is not subscriptable

hi @Tahir - this is because

State

was not generic but was being treated like a generic (i.e. this is a bug we have fixed) can you upgrade

prefect-dask

like this?

pip install -U 'prefect[dask]<3'

prefect[dask,dbt,shell]==2.20.7

This solved it! Thanks
