It errors as expected for me:
```
Traceback (most recent call last):
File "/tmp/throwaway.py", line 4, in <module>
open("someDirectory")
IsADirectoryError: [Errno 21] Is a directory: 'someDirectory'
```
Are you able to write a simple file instead?
```
import pathlib
pathlib.Path("throwaway.txt").write_text("Test successful")
```
