About challenge #1 explotation

[AnaRhisT94]

I'm trying to exploit it with:
await this.token.transfer(this.pool.address, INITIAL_ATTACKER_BALANCE, {from: attacker});

Which doesn't work.

But if I use it w/o from:attacker it works:

    `await this.token.transfer(this.pool.address, INITIAL_ATTACKER_TOKEN_BALANCE);`

Why is that?
