@peterzhuamazon can you please help with this issue?
With these changes upload of codecov is failing with

[2024-11-06T01:12:03.492Z] ['error'] There was an error running the uploader: Error uploading to [https://codecov.io:](https://codecov.io/) Error: There was an error fetching the storage URL during POST: 429 - {"message":"Rate limit reached. Please upload with the Codecov repository upload token to resolve issue. Expected time to availability: 1303s."}

I was checking your PR codecov/feedback#525 and copied changes from opensearch-project/dashboards-flow-framework#401 to neural-search repo.

Before this change codecov action was failing with different issue: {"message":"Repository not found"} https://github.com/opensearch-project/neural-search/actions/runs/11616264178/job/32348813055?pr=971

There might be more tweaks tho.

@martin-gaievski Can you confirm whether this is due to flakey tests?

@peterzhuamazon it may be the case we need additional tweaking for neural search, could you please take a look?
