[BUG] Poll not sent during exercise on Discord

[ralfkairos]

Describe the bug
Impossible to start the exercise with docker + Discord channel & bot. The Poll is generating an error in the logs
bot is correctly configured and present in the channel.
bug happens with Gui enabled, log view is started.
When I click on start on GUI interface:
"Failed, Token was not provided or is not an integer."

sudo docker run --rm -t --env-file .env -v $(pwd)/MSEL.json:/app/MSEL.json -p 5000:5000 base4sec/t3sf:discord

MSEL config file is:
{
"#": 1,
"Real Time": "07:30 PM",
"Date": "Monday 9:40 AM",
"Subject": "[URGENT] Ransom Request!",
"From": "SOC - BASE4",
"Player": "Legal",
"Script": "Team, we received a ransom request. What should we do?",
