Deployment of FlashLoan-Box is failing

[AtticusLScott]

Hi. I am following the tutorial https://docs.aave.com/developers/tutorials/performing-a-flash-loan/...-with-truffle.

After to do "migrate --reset", I am getting the following error:

Starting migrations...

Network name: 'ropsten' Network id: 3 Block gas limit: 8000000 (0x7a1200)

1_initial_migration.js

Deploying 'Migrations'

**Error: *** Deployment Failed *****

"Migrations" -- senderAddress.toLowerCase is not a function.

Please, Can you review?
