Assert return value of `expected_http_error`

[toslunar]

expected_http_error returns bool | None to be tested. https://github.com/jupyter-server/jupyter_server/blob/c5dc0f696f376e1db5a9a0cbcebb40a0bf98875c/tests/utils.py#L24-L45

Thanks you @toslunar!

We looked at this in the Jupyter Server meeting this week and we'll follow up soon. cc @matthewwiese

@Zsailer The four tests fail because of the use of try/except within post() (here)

test_post_event_400() is called using four payloads and is expected to fail because:

• payload_3, payload_4, and payload_5 are all missing one of data, version, or schema_id
• payload_6 has a timestamp entry not formatted in ISO with UTC offset (see here)

You can see in the error message for payload_6 that a 400 is correctly raised, but is caught by the try/except block and changed to a 500.

If the try/except block is modified to raise HTTPErrors as they are, then all tests pass:

try:
    validate_model(payload)
    self.event_logger.emit(
        schema_id=payload.get("schema_id"),
        data=payload.get("data"),
        timestamp_override=get_timestamp(payload),
    )
    self.set_status(204)
    self.finish()
except web.HTTPError:
    raise
except Exception as e:
    raise web.HTTPError(500, str(e)) from e

Thanks, @matthewwiese! The modification to the try/except block looks right to me.

I've added you to our list of collaborators—so you can push directly to this PR/branch. If you or @toslunar can update this PR to get the tests passing, I'm happy to merge. Thanks!

Looks like the jupyterlab_server tests are failing (link) all with the same error: AttributeError: module 'jsonschema._utils' has no attribute 'load_schema'

[toslunar]

@matthewwiese Thank you for fixing the code!

[matthewwiese]

@toslunar Thank you for submitting a PR! :)

@Zsailer Do you have an idea for what's causing the jupyterlab_server tests to fail? I took a brief look and it appears it might be related to packages/dependencies?

[blink1073]

@matthewwiese I believe the errors are related to https://github.com/jupyterlab/jupyterlab_server/issues/400.
