DeFi Protocol Deep Dive - Lesson 1 - Error: Unhandled Rejection (AssertionError): Symbol "MDAI" is not recognized

I have noticed there is an error after following all the steps from the lesson towards the end and clicking ‘Connect With Metamask’. As shown in the image.

Any idea how I can get the same result as on the lesson?


Same thing for me.
It seems it is not able to find MDAI token:
let MDAIBalance = await maker.getToken(‘MDAI’).balanceOf(maker.currentAddress());
Maybe the code is old and needs to be updated?

That could be the case
