What may be the possible issue?

@Cryptobaba1 Please verify code from GitHub repo and youtube video. Otherwise post your scripts, hardhat config file, helper file etc. So we can find the issue.

@Cryptobaba1 I see your all scripts and config files print the chainId after getting it from the network config and add other check points so we can check where is the actual issue. And last after doing so show me the whole terminal result.

Hey @ali-thegilfoyle I finally Figured out what is the issue is

In hardhat.config.js
RINKEBY_RPC_URL the name I am using is a slight diff in my .env
RINKBEY_RPC_URL that's created the Issue

Anyway Thank you Bro
