اسم ملف ICS غير محدد

Overview

When clicking “Add to calendar” in the event preview modal (the one that appears after clicking on the event’s date), the downloaded .ics file is named undefined.ics and the event title inside the calendar file is also set to SUMMARY:undefined. However, downloading the calendar via the “Add to calendar” option from the event’s 3-dot menu works as expected, using the event’s title for both the filename and the calendar summary.

Steps to reproduce

1. Create or open a topic with an event

2. Click on the event date shown in the post to expand the preview modal:
   

   

3. In the modal, click on Add to calendar

4. Save the generated .ics file.

5. Optionally, compare by clicking on the event’s 3-dot menu and using Add to calendar from there

Expected results

• The downloaded .ics file should be named after the event’s title
• The calendar file content should have a correct SUMMARY: with the event title

Observed results

• The downloaded file is named undefined.ics
• The event title in the calendar file is SUMMARY:undefined
• (When downloaded from the 3-dot menu, both filename and summary are correct.)

Additional context
