On some circumstances, the bot mattermost for agiledashboard fails to retrieve the chosen bot. Agile Dashboard is not published on mattermost.
2021-01-15T11:03:32+01:00  [error] : No bot found:
#0 /usr/share/tuleap/plugins/botmattermost_agiledashboard/include/BotMattermostAgileDashboard/BotMattermostStandUpSummary/Factory.php(127): Tuleap\BotMattermost\Bot\BotFactory->getBotById('5')
I can't provide exact steps to reproduce. I suspect that many bots and dashboard notifications have been created.
