Can't download files from large zip via endpoint: "Internal Server Error"

[cccoolll]

After I uploaded large zip files ( >200MB, >4000 chunk files) to our Artifact Manager. I can browse contents via zip endpoints. However, when I try to download a file via zip endpoint, it returns '500 Internal Server Error'.

Steps I did to reproduce issue:

1. Upload a large .zip file which include OME-Zarr file set to Artifact Manager ( >200MB, >4000 chunk files).

2. Use the zip endpoints to browse its contents — it works currently.

3. Try to download a file inside the zip → 500 Internal Server Error.

Example endpoints(which returns 'Internal Server Error'):

Uploaded via multipart uploading: https://hypha.aicell.io/agent-lens/artifacts/test-20250820-140726/zip-files/well_A1_96.zip/~/data.zarr/.zattrs

Upload via 'put_file': https://hypha.aicell.io/agent-lens/artifacts/example-cell-data-20250723-122839/zip-files/well_F5_96.zip/~/data.zarr/.zattrs

Working endpoint(small zip file ~10MB): https://hypha.aicell.io/agent-lens/artifacts/default-20250820-133017/zip-files/well_A11_96.zip/~/data.zarr/.zattrs

@oeway Could you try these links and check logs in the Hypha server? So that we can identify the error, and decide which direction we can move on to fix this issue.

The zip file should been fixed now, please confirm, at least it works with this test: https://github.com/amun-ai/hypha/blob/7cd03c0a4b9b47d4cc879f268c236a7552efab6a/tests/test_artifact.py#L3687-L3829
