Invalid genesis.json file

[berenerchamion]

When I attempt to init the genesis block, I get the following error:

invalid genesis file: json: cannot unmarshal non-string into Go struct field ChainConfig.config.eip150Hash of type common.Hash

I think you have to have an actual value on that line and not just 0. This works:
"eip150Hash": "0x0000000000000000000000000000000000000000000000000000000000000000",
