Hi, I just started to learn how to build a bot on botpress, i am in the middle of making some progress, but stuck on a KB issue, I just tried a lot of ways to try to get the result that I wanted. Then, suddenly, the error message popped up, I have used up my token quote on the free version, since i am still learning, I can buy 5000 invocations, but i am too scared to try it or experiment like i did before. Does anyone else has the same issue like mine? or anyone who has a workaround for this issue just for practise to build bots without spending a fortune on it?
