@HardlyDifficult ID at this point is 0, but should actually be a valid tokenID!
D0 we need to "wait" for mining before querying the contract perhaps?

@HardlyDifficult I'm stuck on this atm...here's the latest build log. https://circleci.com/gh/unlock-protocol/unlock/46868?utm_campaign=vcs-integration-link&utm_medium=referral&utm_source=github-build-link As you can see, 2 failing tests. The second one is Uncaught Error: Returned values aren't valid, did it run Out of Gas? at ABICoder.decodeParameters (node_modules/truffle/build/webpack:/~/web3-eth-abi/src/index.js:226:1) which shows up in a thread about a web3 error : web3/web3.js#1916 (comment)

I need to take a break from this, it's killing me. If you know what's going on here off the top of your head, well that would be swell.

[HardlyDifficult]

That second error, 'out of gas', is because of the first error. So that's the one to focus on. hmm I'm not sure which line is failing though - wish the stack trace didn't suck =p.

Maybe add some console logs to narrow it down

[nfurfaro]

Yeah the stack trace does suck. Ive been playing with adding console.logs, as well as commenting out lines, to try to isolate the failure. Will keep at it after a break.

[HardlyDifficult]

@nfurfaro fixed the gas report - sorry for the trouble. not exactly sure how it was working previously ;)

[nfurfaro]

@HardlyDifficult Thanks! I wasn't sure what was causing that error, but happy to move on!
