until is before since, so the range names no events. This is an HTTP 422: the request parsed but a value is not acceptable.

## Troubleshooting

- Check this endpoint’s request schema in the API reference; `param` in the response names the exact field at fault.
- Use an official SDK, which enforces required fields and types before the call is made.
