[Bug Report] v5 Tasks PATCH endpoint returns HTTP 500 when `links` field contains entries

Product

Akiflow API — https://api.akiflow.com/v5/tasks

Summary

Sending a PATCH request to the v5 tasks endpoint with a non-empty links array results in HTTP 500. An empty links: [] is accepted without error. There is no way to attach links to a task via the v5 API.

More information, reproduction steps and code samples in the attached document.

Expected behavior

The task is updated with the provided links, which then appear in the task's "Links" section in the Akiflow web and desktop apps.

Actual behavior

HTTP 500 is returned when links contains one or more entries. No error body is returned — just a 500 status code.

Question

Is there a separate endpoint for managing task links (e.g. POST /v5/tasks/{id}/links)? If so, documentation on this endpoint would be helpful. If links are intended to be set via the tasks PATCH endpoint, the 500 appears to be a server-side bug.
