Hello Zoho Support Team,

We are experiencing a reproducible HTTP 500 Internal Server Error when querying the Zoho Desk API search endpoint with a specific modifiedTimeRange boundary.

### API Endpoint

GET /api/v1/tickets/search

### Reproduction Steps & Test Cases

1. Success Case (Before boundary):

- modifiedTimeRange: 2026-03-08T01:58:00.000Z, 2026-03-08T01:59:59.000Z

- Result: HTTP 204

2. Failure Case (Hitting the boundary):

- modifiedTimeRange: 2026-03-08T01:59:59.000Z, 2026-03-08T02:00:00.000Z

- Result: HTTP 500

- Response body: {"errorCode":"INTERNAL_SERVER_ERROR","message":"An internal server error occurred while performing this operation."}

3. Success Case (After boundary):

- modifiedTimeRange: 2026-03-08T02:00:00.000Z, 2026-03-08T02:00:01.000Z

- Result: HTTP 204

### Additional Diagnostic Findings

- Removing sortBy still produces an HTTP 500.

- Removing from still produces an HTTP 500.

- Both limit=1 and limit=100 trigger the error.

- Adjacent time ranges and general API requests function normally (HTTP 200/204).

- The failure isolates specifically to the timestamp 2026-03-08T02:00:00.000Z.
