Bug: Events page shows 'Something went wrong' - API returns 400 due to null values

[supg]

Description

The Events page on a self-hosted OpenPanel instance displays "Something went wrong" error. The dashboard is sending null values for optional API parameters instead of omitting them, causing Zod validation failures.

Environment

• OpenPanel: Self-hosted via Kubernetes (k3s)
• Images: lindesvard/openpanel-api:latest, lindesvard/openpanel-dashboard:latest
• Pulled: January 24, 2026

Console Error

TypeError: Cannot destructure property 'name' of 't.original' as it is undefined.

API Response (400 BAD_REQUEST)

{
  "error": {
    "json": {
      "message": "[{\"code\":\"invalid_type\",\"expected\":\"string\",\"received\":\"null\",\"path\":[\"profileId\"]},{\"code\":\"invalid_type\",\"expected\":\"string\",\"received\":\"null\",\"path\":[\"cursor\"]},{\"code\":\"invalid_type\",\"expected\":\"date\",\"received\":\"null\",\"path\":[\"startDate\"]},{\"code\":\"invalid_type\",\"expected\":\"date\",\"received\":\"null\",\"path\":[\"endDate\"]}]",
      "code": -32600,
      "data": {
        "code": "BAD_REQUEST",
        "httpStatus": 400,
        "path": "event.events"
      }
    }
  }
}

Network Request

The dashboard sends:

/api/trpc/event.events?input={"json":{"projectId":"time-tracker","filters":[],"events":[],"profileId":null,"startDate":null,"endDate":null,"cursor":null}}

Note: The first request includes meta.values that maps nulls to undefined (returns 200), but a second request without the meta section fails with 400.

Expected Behavior

Events page should load and display events.

Actual Behavior

Page shows "Something went wrong" error due to API validation failure.

Steps to Reproduce

1. Navigate to Events page on self-hosted instance
2. Page immediately shows "Something went wrong"
3. Check browser console for TypeError
4. Check network tab for 400 response on event.events API call

Workaround Attempted

• Restarted dashboard and API pods - no change
• Verified ClickHouse and other services are healthy
