Lesson 7 Cannot read properties of undefined (reading 'includes')

[RomeDomeYome]

Upon deploying the test contract with 00-deploy-mocks.js i get this error:

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

on this line of code:

if (developementChains.includes(network.name))

Im not really sure what to make of it. It seems like I imported developement chains from helper.hardhat.config.js just fine. What gives?

can you share the entire code for 00-deploy-mocks.js and helper-hardhat-config.js

i just figured it out. i spelt it as developmentChains in helper-hardhat and as developementChains when importing it. Silly mistake 🤦

Spelled developmentChains wrong
