Here's a list of common things to rule out when troubleshooting issues:
- first, make sure you have carefully followed all steps in the README.
- are you up to date on the latest git commit?
- have you run npm install and npm build --prefix functions since the last time you pulled from git?
- have you setup your .env file as described in the readme including the functions API endpoint?
- is one and only one instance of your emulator running (on the ports expected)?
- have you created a user group in treat toolbox?
- have you setup traits, values for each trait, and artwork, and mapped each piece of artwork to a trait and trait value?
- are the rarities of your trait values set between 0 and 1?
- do you have enough trait values setup so that multiplying the number of trait values together for each trait exceeds your requested supply? (ideally significantly exceeds to account for things like conflict resolution)
- are your art files all PNGs?
- do you have adequate disk space to generate lots of PNGs?
- what version of java are you running? (on mac have you tried OpenJDK through homebrew?
