test failures unrelated :sadge:

[drakejwong]

trying to fix failures here! #347

[drakejwong]

lgtm 🙌 but we'll probably need to rebase once #347 lands for CI fixes

might also consider adding some e2e tests / filling a followup ticket to add

[anthonykrivonos]

@drakejwong Def, here's the ticket for test improvements: https://app.shortcut.com/scaleai/story/549800

@drakejwong after yesterday evening's rebase tests still fail 🤔 cc @jihan-yin bc failures are coming from test_update_autotag and test_slice_create_and_prediction_export

[drakejwong]

@jihan-yin looks like the update_autotag test is still failing with

{"status_code":404,"error":"Nucleus Autotag with id tag_c8jwr0rpy1w00e134an0 not found! When reporting an issue add the request_id:'dea8f877-9bef-9631-8a35-2ce65b5c464e'"}

even though the backend changes should have made it into today's deploy :(

i'll look into the export_predictions failure, i think there might've been a backend regression since it's now failing consistently (but wasn't until recently)

[drakejwong]

@anthonykrivonos test_segmentation_pred_upload is still flaky so i just reran CI and it passed — have a ticket to investigate

test_slice_create_and_prediction_export and test_update_autotag were actually broken though and have now been fixed! appreciate your patience on these good sir 🙏

[anthonykrivonos]

@drakejwong Ah gotcha, welp thanks for the merge 🙌
