2 cases:

1. Create a new bounty on the web and publish it. Error in DiscordUtils.refreshLastList trying to get user from request.buttonInteraction
2. Publish a bounty on the web created as a draft on the bot. To do this you need to copy the bounty ID on the bot, and go to /. Click Publish. Get same error
