[SOLVED] Lesson 7: ReferenceError: MockV3Aggregator is not defined

[nsawit]

All .sol files compiled successfully (FundMe, PriceConverter and MockV3Aggregator). However, I am getting this error when trying to deploy mocks.

Error details:
Nothing to compile
Local network detected!
An unexpected error occurred:

Error: ERROR processing /Users/ns/Blockchain/hardhat-fund-me-fcc/deploy/00-deploy-mocks.js:

it's now working. Found out that I wrote 'arguments' instead of 'args' in 00-deploy-mocks.js

 if (developmentChain.includes(network.name)) {
        log("Local network detected!")
        await deploy("MockV3Aggregator", {
            contract: MockV3Aggregator,
            from: deployer,
            log: true,
            arguments: [DECIMAL, INITIAL_ANSWER], // changed it to **args**
        })
        log("LOGGGING MOCKS DEPLOYED")
        log("******************************************")
    }
