```
But file uploaded.

## Setup

Use the docker-compose file:

[docker-compose.yml.zip](https://github.com/owncloud/ocis/files/12484851/docker-compose.yml.zip)

And the Dockerfile + etc from clamav:

[Archive.zip](https://github.com/owncloud/ocis/files/12484861/Archive.zip)

Start with services/antivirus/pkg/service/service.go, especially the scan flow around lines 132, 160, 177, and 217, then reproduce the failure using the attached docker-compose.yml and Archive.zip setup. Trace how the antivirus download error is reported to the upload flow and UI. Done means an antivirus processing error prevents the file from being uploaded and surfaces an error to the user.
