Can you make a repo and link it here? I will look into it.

[aviral727]

yeah sure I'll do it asap currently I'm afk

[othaime-en]

Could you please share your 00-deploy-mocks.js code with us?

[aviral727]

here's the repo please have a look

[alymurtazamemon]

@aviral727 Could you please follow these guidelines next time when you ask a question? How to Ask Question Guide

[alymurtazamemon]

@aviral727 It is module.exports make sure to correct it inside 00-deploy-mocks.js

[alymurtazamemon]

@aviral727 mark the answers that solve your issues, so we can filter them out.

[aviral727]

sure

[othaime-en]

I don't see any error other than the typo module.export instead of module.exports in your 00-deploy-mocks.js

[othaime-en]

In Line 4

[aviral727]

I see my my mistake was the typo error at module.export but why is it that the main repo by Patrick sir has module.exports and it works? What is the difference?

[othaime-en]

What error?

this one

[othaime-en]

The developmentChains array at helper-hardhat-config.js doesn't have chainIds, only names. So try and replace the if statement in your 00-deploy-mocks.js file from if(developmentChains.includes(chainId)) to if(developmentChains.includes(network.name)) and see if it will work

[othaime-en]

Oh. and... you also forgot to export the developmentChains array from your helper-hardhat-config.js That's probably whats causing the undefined error

[aviral727]

alright I'll look into it
