Lesson 7: cannot estimate gas; transaction may fail or may require manual gas limit while runing fund script

[Codeinor]

[NagoriMustakim]

make this correction

value: ethers.utils.parseEther("0.1"),

[Codeinor]

still same error

[Muhammad-Abdullah012]

What is minimum fund amount??
You're sending value less than the minimum allowed in your contract.

[Muhammad-Abdullah012]

@Codeinor I've seen your repo now, Your minimum allowed Funds are 5 ethers, so try changing your code to :

value: ethers.utils.parseEther("5")

[Codeinor]

it's working thank you!

@Codeinor try to add gas like this, otherwise push the code to GitHub and leave a link here I will see it.

rinkeby: {
  url: process.env.RPC_URL,
  accounts: [process.env.PRIVATE_KEY],
  chainId: 4,
  blockConfirmations: 6,
  gas: 6000000,
},

here's my repo

Try Ali's method to manually input a gas limit. If that does not work, reply w/ the repo and we will look into it

I run into the same issue as Codeinor.

I've tried to add gas like here

rinkeby: {
  url: process.env.RPC_URL,
  accounts: [process.env.PRIVATE_KEY],
  chainId: 4,
  blockConfirmations: 6,
  gas: 6000000,
},

for test it worked

$ npx hardhat test --network rinkeby

..but on etherscan rinkeby testnet it failed
Rinkeby testnet contract:

Rinkeby testnet tx:
Status: Fail
" Warning! Error encountered during contract execution [execution reverted] "
