Hangup when calling from FHEM context

[dma7]

I'm using the most recent version of telegram-cli from FHEM on Raspberry Pi. I've registered successfully and when I try to send a message interactively, it works perfectly.

I have created a simple script called sendmsg

!/bin/bash

/opt/fhem/tg/bin/telegram-cli -c /opt/fhem/.telegram-cli/config -vvvv -WR -e "msg $1 $2; safe_quit"

It is execuded from FHEM via the following method sub SendNotificationTelegram($) { my ($str) = @_; system("/opt/fhem/tg/bin/sendmsg user#ABC \"$str\" >/tmp/tg.log"); }

The script is also working when it is called from pi's context.

When I call it from FHEM it seems to hang up. Looking into tg.log shows the following output:

Do you have any idea how to get it working?

In the meantime, I was able to fix the issue myself.

In FHEM, I had to change the call of my script to the below

system("sudo -u fhem /opt/fhem/tg/bin/sendmsg user#ABC \"$str\" >/tmp/tg.log"); }
