[QA] OCM: upload into received federated folder shows an error

[jnweiger]

Describe the bug

A user who received a shared folder via federation cannot view images. The image viewer hangs

Steps to reproduce

Setup two federated machines with e.g.

env OCIS_DNSNAME=dog-DATE OCIS_VERSION=daily ./deploy_ocis_bare_metal.sh
env OCIS_DNSNAME=cat-DATE OCIS_VERSION=daily ./deploy_ocis_bare_metal.sh
ocm_trust.sh dog-20241015.jw-qa.owncloud.works cat-20241015.jw-qa.owncloud.works

• admin adds the instances to each other's ocmproviders.json .
• user alice at cat visits the sciencemesh app and create an invite token for user bob at dog.
• user bob at dog enters the token, and shares a folder smallpics (continaing some png and jpg images) with alice ad cat
• user alice clicks Shares in the left sidebar, and clicks smallpics ( see [QA] OCM - a federated folder randomly shows 'enable sync' message #10271 )
• user alice uploads a folder (with 15 files) into the received share. The upload succeeds, but an error is shown:

• Clicking on 'details' make the error disappear, instead of showing details. BAD
