Check Existing Issues

  • I have searched for any existing and/or related issues.
  • I have searched for any existing and/or related discussions.
  • I have also searched in the CLOSED issues AND CLOSED discussions and found no related items (your issue might already be addressed on the development branch!).
  • I am using the latest version of Open WebUI.

Installation Method

Docker

Open WebUI Version

v0.9.5

Ollama Version (if applicable)

No response

Operating System

Debian 12

Browser (if applicable)

No response

Confirmation

  • I have read and followed all instructions in README.md.
  • I am using the latest version of both Open WebUI and Ollama.
  • I have included the browser console logs.
  • I have included the Docker container logs.
  • I have provided every relevant configuration, setting, and environment variable used in my setup.
  • I have clearly listed every relevant configuration, custom setting, environment variable, and command-line option that influences my setup (such as Docker Compose overrides, .env values, browser settings, authentication configurations, etc).
  • I have documented step-by-step reproduction instructions that are precise, sequential, and leave nothing to interpretation. My steps:
  • Start with the initial platform/version/OS and dependencies used,
  • Specify exact install/launch/configure commands,
  • List URLs visited, user input (incl. example values/emails/passwords if needed),
  • Describe all options and toggles enabled or changed,
  • Include any files or environmental changes,
  • Identify the expected and actual result at each stage,
  • Ensure any reasonably skilled user can follow and hit the same issue.

Expected Behavior

At the exact start time of the calendar event, a notification should be displayed in the GUI, and the associated webhook should be executed.

Actual Behavior

  1. Nothing happens at the scheduled time.
  2. No notification is shown in the Open WebUI.
  3. The webhook is not triggered.
  4. Crucially, the logs remain empty regarding this event, indicating the trigger might be skipped entirely.

Steps to Reproduce

  1. Create a new calendar event.
  2. Set the Reminder to "At time of event".
  3. Wait for the event start time.

Logs & Screenshots

No relevant logs.

Additional Information

Working as expected: Reminders set to other intervals (e.g., 5 minutes or 10 minutes before the event) work perfectly fine - both the UI notification and the webhook trigger as intended.
The issue seems specifically isolated to the "At time of event" logic.

I found some existing issues that might be related. Please check if any of these are duplicates or contain helpful solutions:

  1. 🟣 #23965 feat: add reminder time as a parameter to create_calendar_event
    This feature request is directly about calendar event reminders and adding reminder-time control to create_calendar_event. It is closely related because the new bug concerns a specific reminder timing option ('At time of event') not triggering notifications or webhooks.
    by DanielHe212

  2. 🟢 #24079 enh: calendar
    This open calendar enhancement appears to cover the broader calendar subsystem where reminder behavior is implemented. It is relevant as a likely umbrella issue for calendar-related fixes, including reminder timing edge cases.
    by tjbck

  3. 🟢 #1240 feat: additional webhook events
    This issue is about adding additional webhook events, which is tangentially related because the reported bug is specifically that the calendar reminder should fire a webhook and does not. It may help track webhook-trigger coverage for calendar events.
