[BUG] GraphQL Exception after pip install and running quickstart example

[sourcesync]

Describe the problem

I ran the pip install quickstart example and got this GraphQL exception:

GraphQL API Error
Cannot return null for non-nullable field Query.dataset.

Here is the exception stack:

File "/Users/cuongwilliams/anaconda3/envs/voxel51/lib/python3.10/site-packages/graphql/execution/execute.py", line 1038, in await_result
    return build_response(await result, errors)  # type: ignore
  File "/Users/cuongwilliams/anaconda3/envs/voxel51/lib/python3.10/site-packages/graphql/execution/execute.py", line 453, in get_results

  File "/Users/cuongwilliams/anaconda3/envs/voxel51/lib/python3.10/site-packages/graphql/execution/execute.py", line 537, in await_result

  File "/Users/cuongwilliams/anaconda3/envs/voxel51/lib/python3.10/site-packages/graphql/execution/execute.py", line 622, in complete_value
    raise TypeError(

Code to reproduce issue

I created a python=3.10 using conda and activated it.

Then I ran the following code:

import fiftyone as fo
import fiftyone.zoo as foz

dataset = foz.load_zoo_dataset("quickstart")
session = fo.launch_app(dataset)

System information

• MacOSX Sequoia 15.2 on M2 MacBook
• Conda 24.1
• Python =3.10
• fiftyone ==1.2.0
• fiftyone-brain == 0.18.2

Hi @sourcesync. Thanks for the report. What version of strawberry-graphql do you have? The below should work.

pip list | grep "strawberry"

or

conda list | grep "strawberry"

It is surprising to the see this issue. I am unable to reproduce. Clearing your browser cache may help, as well

Yep. Let me know if you need anything else.

% python -m pip list | grep -e voxel -e strawberry -e fifty
fiftyone                    1.2.0
fiftyone-brain              0.18.2
fiftyone_db                 1.1.7
strawberry-graphql          0.258.0
voxel51-eta                 0.13.1

Are you running the code in a script? If so, you will need to use session.wait() to keep the process alive.
