Describe the bug

Opening a Markdown file through a public, read-only folder share gets stuck on the loading screen when Deck is enabled.

The file is a regular Markdown document, unrelated to any Deck card. Disabling Deck makes the same anonymous preview work immediately. Opening the file as an authenticated user also works.

The public Text session is created successfully, but subsequent sync and save requests fail with HTTP 500:

OCA\Deck\Provider\TextContextProviderFactory::__construct():
Argument #5 ($userId) must be of type string, null given

The following behavior was verified:

Deck | Access | Result -- | -- | -- Enabled | Anonymous public share | Loading screen; HTTP 500 Disabled | Anonymous public share | Works Enabled | Authenticated user | Works

Possible cause: the implementation introduced in PR #8558 injects TextContextProviderFactory into RegisterTextContextEventListener, although the listener only registers the factory's class name and does not use the injected instance. This appears to instantiate the factory prematurely during context registration, including for ordinary public file sessions. Its constructor requires a non-null string $userId, which is unavailable for anonymous requests.

Removing the unused constructor dependency from the registration listener looks like a possible fix, but this has not been tested locally.

To Reproduce

Steps to reproduce the behavior:

  1. Enable Deck.

  2. Share a folder containing a Markdown file using a public, read-only link.

  3. Open the link without logging in.

  4. Navigate to the Markdown file and click it.

  5. Observe the persistent loading screen and HTTP 500 responses from the public Text sync and save endpoints.

  6. Disable Deck and repeat the anonymous access: the same file displays successfully.

The failing anonymous access was reproduced from a separate virtual machine.

Expected behavior

Public Markdown previews should work while Deck is enabled, without requiring an authenticated Nextcloud user.

Operating system:

Arch Linux.

Web server:

Traefik reverse proxy in a Docker Compose deployment. Captured HTTP responses contain the server header nginx.

The deployment consists of a reverse proxy, a Nextcloud container, and a separate PostgreSQL container.

Database:

PostgreSQL, using the Docker image postgres:latest. The exact runtime version has not been recorded.

PHP version:

8.3.36, according to the HTTP response header.

Nextcloud version: (see Nextcloud admin page)

35.0.1; internal version: 35.0.1.1.

Where did you install Nextcloud from:

Arch Linux package installed using:

pacman -S nextcloud

The deployment is managed through Docker Compose.

Signing status:

The integrity check reports two extra files in the Nextcloud root directory:
