Coursera project

can you help me with IBM Watson Assistant. I am completing a course on Coursera taught by IBM but the instructions are 'buggy'. I have developed the entities, dialogs etc. but am getting an error message which i cannot understand. Also having difficult connecting to Facebook and Slack- happy to connect and pay on an hourly or project basis, no matter if the problems take less time to fix. I imagine it is a simple solution. If there is time left over, you can add some exciting GUI- I can send you all information ( usernames, passwords, APIkeys, APIsecrets for Facebook & Messenger)
