Relevant log output

>               content = np.array(content, copy=False, dtype=str).tolist()
E               ValueError: Unable to avoid copy while creating an array as requested.
E               If using `np.array(obj, copy=False)` replace it with `np.asarray(obj)` to allow a copy when needed (no behavior change in NumPy 1.x).
E               For more details, see https://numpy.org/devdocs/numpy_2_0_migration_guide.html#adapting-to-changes-in-the-copy-keyword.

Additional context

The tests are failing probably due to switch to numpy 2.x, there is a PR upstream that fixes it

I suggest you open a PR that uses fetchpatch to apply that patch.

That was my initial intent though I wasn't sure if it's okay to fetch a patch which isn't merged yet. I will raise a PR then.
