unexpected EOF, missing quote or backtick?

Question

I'm working on a script that in use with other scripts can send system or other notifications through Telegram , the script pulls the data from domoticz .

I'm sure i'm missing a quote or backtick somewhere but i hope someone is kind enough to read over the small script and provide a fresh pair of eyes to see where i messed up:

#!/bin/bash

# Settings
TelegramSendMsg="/opt/telegram/scripts/generic/telegram.sh"
TmpFileName="/opt/telegram/scripts/tmp/SystemStatus.txt"
SendMsgTo=$1

#Send sensor values with telegram

Answer 1

Stackoverflow's syntax highlite tells that something wrong here

ResultString+=`curl "http://192.168.1.141:8086/json.htm?type=devices&rid=8" 2>/dev/null` | jq -r .result[].Data`

It is backtick here

null`
