Lesson-9: Error: TypeError: Cannot read properties of undefined (reading 'length')

[umair-mirza]

After creating both deployment scripts:

• 00-deploy-mocks.js
• 01-deploy-raffle.js

When I finally run
yarn hardhat deploy

The script deploys successfully:

---

Local network detected! Deploying Mocks..
deploying "VRFCoordinatorV2Mock" (tx: 0x11b9dfa83e5a81e783d8d818bd6499fa1504a937113eca5f07b8cfafe70751ea)...: deployed at 0x5FbDB2315678afecb367f032d93F642f64180aa3
with 1797707 gas
Mocks Deployed!

---

And right after I get this error:

---

TypeError: Cannot read properties of undefined (reading 'length')

at _deploy (E:\Web3 Projects\raffle\node_modules\hardhat-deploy\src\helpers.ts:533:9)

I've tried to Google the issue but to no avail. What could be the issue? The Mock contract gets deployed fine but why does it also give an error afterwards?

Could you send the code for your 01-deploy-raffle.js file?

Oh I think it's fixed now. I saw another similar question posted in this Repo's discussions.
The problem was getNamedAccounts() was missing '()'.

Thanks for getting to me so quick :)

That's great! Goodluck with the course.

Thank you! It's going great!
