Lesson 10: I am not getting the recent winner

[umairahmed88]

When I yarn hardhat run scripts/mockOffchain.js --network localhost
It does not give me the recent winner

I copy the mockOffchain file from Patric's github file,
this is the response

yarn hardhat run scripts/mockOffchain.js --network localhost
yarn run v1.22.19
warning package.json: No license field
$ /home//hardhat-practice/hardhat-smartcontract-lottery/node_modules/.bin/hardhat run scripts/mockOffchain.js --network localhost

Hi @umairahmed88

As you are running it on localhost network, so you should define it in your hardhat.config.js file like below:

    networks: {
        hardhat: {
            chainId: 31337,
            blockConfirmations: 1,
            // gasPrice: 130000000000,
        },
        localhost: {
            chainId: 31337,
            blockConfirmations: 1,
        },

It also seems like your checkUpkeep function throws false, so you can take a look at that too to print if it throws false or true and correct it if it throws fail.

Thank you! It worked
I was waiting for it from three days

I am facing the same problem here; upkeepNeeded is always returning false. Could anyone help, please?

@shureedshazzad

Should we guess whats the logic in your checkUpkeep function? First of all post new discussion, paste all necessary code parts and link your repo. Anyway if your checkUpkeep return false then you did not meet all requirements and you should first of all tests if all if returning true.

Thanks Brother . I will post new discussion.
