[sillitatti]

⚠️ This issue respects the following points: ⚠️

• This is a bug, not a question or a configuration/webserver/proxy issue.

Bug description

Opening the Files app in the browser with browser E2EE enabled and an encrypted folder created results in an error:

"Unexpected error: Invalid response: No root multistatus found".

In the server log there is an error:

"Error
no app in context
NotFoundException /appdata_ocyxgogqr83a/end_to_end_encryption/meta-data/197"

Plus an identical one for WebDAV.

I'm on 32.0.9 and successfully recreated this with a fresh installation.

Steps to reproduce

1. Enable end-to-end encryption on the server
2. Create an encrypted folder in the Android client
3. Enable E2EE in the browser in Personal settings -> Security
4. Open the files app in the browser

Expected behavior

Browsing files would work as usual, including the encrypted folder.
