[Observium] Telegram Alerts no longer working after Update

Hello!

I have updated Observium to the latest subscription edition (17.6.8663) today.

Since the update our telegram alerts are not working properly. We only get a single zero as text:

Before:

ALERT : Port down

Device: xyz Entity: Port 13 Description: xyz

Device Uptime: 1 year, 118 days, 9h 28s
