Hi all, seeing this error with docker run : Unexpected error: TypeError("'NoneType' object is not subscriptable") Traceback (most recent call last): File "/usr/local/lib/python3.7/site-packages/prefect/engine/runner.py", line 48, in inner new_state = method(self, state, *args, **kwargs) File "/usr/local/lib/python3.7/site-packages/prefect/engine/task_runner.py", line 869, in get_task_run_state logger=self.logger, File "/usr/local/lib/python3.7/site-packages/prefect/utilities/executors.py", line 299, in run_task_with_timeout return task.run(*args, **kwargs) # type: ignore File "<string>", line 519, in delta_push TypeError: 'NoneType' object is not subscriptable Any ideas?

Can you share the output of

prefect version

? Can you share the code that gave you that error?

0.14.10

Why do you use this specific version? Can you upgrade to the latest Prefect 1.0 version which is now at 1.2.2
