I'm on Chapter 3, I started getting this error in around section 15 and this failed error in test is not going away. I am now on section 18 in chapter 3. I have gone back to chapter 2 all sections trying to figure out if I missed something.
When I run test it shows this error that is not in the videos failed test:

at Function.mineBlock (block.js:18:32) at Blockchain.addBlock (blockchain.js:9:32) at Object. (blockchain.test.js:37:28)

If someone could help me figure out why my command prompt the tests can't read properties of hash?
