Steps for Ganache bug

Open multiple terminal tabs, and run the following in each one:
1. `$ ganache-cli` (or if you want the new, not released ganache, follow the steps here: )
2. Pull this repo: https://github.com/graphprotocol/hackathon-scaffold and cd into the ethereum folder
3. Run `$ truffle compile` followed by `truffle migrate` --> it should give you the contract address under "Deploying Events"
4. Copy that address, and paste it into `subgraph.yaml` (subgraph manifest) inside of the hackathon-scaffold project
5. Start `ipfs daemon` in a separate terminal tab
6. Run `createdb scaffold` in another tab to create a database
7. Pull graph-node and run: 
cargo run -p graph-node --release -- \                                                                        13  09:47:43 
  --postgres-url postgresql://nevena@localhost:5432/scaffold \
  --ethereum-rpc testnet:http://127.0.0.1:8545 \
  --ipfs 127.0.0.1:5001 \
  --debug
  8. Inside of your hackathon-scaffold folder, cd into subgraph and run `yarn codegen` followed by `yarn deploy`
  9. Open a separate tab to access Truffle console by running `truffle console --network development`
  10. In the truffle console, run the following to get some accounts: `web3.eth.getAccounts().then(ethaccounts => accounts = ethaccounts)`
  11. Then run the following: `web3.eth.sendTransaction({ from: accounts[0], to: accounts[1], value: web3.utils.toWei('10', "ether"),gas:50000})`
  12. Go back to your graph-node terminal tab, and you should get hte following logs:
  WARN Trying again after block polling failed: could not get latest block from Ethereum: Decoder error: Error("invalid type: null, expected a 0x-prefixed hex-encoded vector of bytes", line: 0, column: 0)
 Nov 08 09:57:27.216 WARN Trying again after block polling failed: could not get latest block from Ethereum: Decoder error: Error("invalid type: null, expected a 0x-prefixed hex-encoded vector of bytes", line: 0, column: 0)
 13. Run `curl -s http://127.0.0.1:8545 -d '{"jsonrpc":"2.0","id":1,"method":"eth_getBlockByNumber","params":["0x7",true]}'`
 and you should get:
