[BUG]App error with database_uri config

[KirigiriSuzumiya]

Describe the problem

the app page shows network error code 500. I got traceback like this in the graphql request

  File "/home/stardust/miniconda3/envs/fiftyone-dev/lib/python3.12/site-packages/fiftyone/server/context.py", line 40, in get_context
    return get_context(request=request, response=response)

    raise FiftyOneConfigError(
fiftyone.core.config.FiftyOneConfigError: MongoDB could not be installed on your system. Please define a `database_uri` in your `fiftyone.core.config.FiftyOneConfig` to connect to yourown MongoDB instance or cluster 

But refer to the code I provided, fo.list_datasets() works well, which did get data from my mongodb, can anyone help?

Code to reproduce issue

import fiftyone as fo

if __name__ == "__main__":
    fo.config.database_uri = "mongodb://root:passwd@localhost:27017"
    fo.config.database_validation = False
    print(fo.list_datasets())
    # this works well , I get my dataset
    session = fo.launch_app()
    session.wait()

Provide a reproducible test case that is the bare minimum necessary to generate the problem. Please avoid sharing code that relies on your local data or datasets. Include a short video or screenshot if the bug is in the App.

my web page shows this:

HI @KirigiriSuzumiya. This is an issue with the server startup process which we are looking into. Defining the db settings as an environment variable before running your script should avoid the problem.

export FIFTYONE_DATABASE_URI=mongodb://root:passwd@localhost:27017
export FIFTYONE_DATABASE_VALIDATION=false
