I followed the instructions from https://botpress.com/docs/integration/getting-started/ When I try to do the last bp dev (the one before you do bp deploy) I get an error saying: 'ua is not a constructor'. When i remove the 'new' in the next part of my code the error changes to 'ua is not a function'. So it appears something is wrong with my integration. I started over the whole tutorial but get the same error. Is the tutorial still valid? const bot = new Bot({ integrations: [ new botpressVoorbeeld({ enabled: true, config: { botToken: '', }, }) ], })
