Can not get my graphQL queries to return data from Replit PosgreSQL db

Question:
I have been trying to debug this for a day or two now and cannot figure it out. A while ago my Replit PostgreSQL db got blown away so had to create it from scratch. Since then my graqhql queries seem not to be working (everything returns null). I have tried looking to fix the resolvers, the data in the dbs, etc. and can not figure it out. Would really love some pointers or help on this! Here is a screenshot of my db contents.
