I am getting ProviderError: HttpProviderError when upgrading my smart contract. I tried changing the RPCs too, but still i get this issue.
Below is my hardhat.config.js

require("@nomicfoundation/hardhat-chai-matchers");
require("@nomiclabs/hardhat-ethers");
require("@openzeppelin/hardhat-upgrades");

Using Hardhat 2.11.0

Did you actually replace RPC_URL, PRIVATE_KEY, and API_KEY when you ran it? This looks like an RPC/Hardhat config issue -- do you get the same error if you just run a deploy for any contract?

3

Yes i get even when i deploy the code

4

I'd just suggest to check your mumbai network config and RPCs again.

5

I was able to deploy once and when i try to upgrade or redeploy proxy i am facing the issue

Hi!
Any updates about this issue? I'm experiencing same problems as Nufail.

I have used the Mumbai RPC url: https://rpc-mumbai.matic.today and the Alchemy configuration exactly as is it in the Alchemy configuration.
With different wallets (PRIVATE KEYS). I can deploy one time and then when redeploy or upgrade, have that error written above.
By the way, RPC/Endpoint is working since before anything I get the blocknumber (await ethers.provider.getBlockNumber())
Thanks!

Hi Charly_Fung, I didn't get a solution for this, you can try creating a new upgradeable project and try it from start.

I face the same issue. In my case it might be the contract size, which became too big.

For local deployment using hardhat I already had to use this setting:

allowUnlimitedContractSize: true,

after my contract reached a specific size. From this point on any deployment wasn't possible on Rinkeby and Mumbai. Unfortunately I got no concrete error message. Removing some functions, so that I could deploy also locally without allowUnlimitedContractSize: true, made it work again deploying also on Rinkeby and Mumbai.

Try to set gasLimit of transactions, that was my problem!!

await mintContract.functions.mint(id, amount, {gasLimit: 40000000});

Hi,
did you find a solution for this?

I have the exactly same error messages even on the demo project. I can deploy to local hardhat network but I can't connect to ganache/mumbai

Hi, welcome to the community! :wave:
So have you tried all ways mentioned above?

12

Hi.
Did anyone find any solution? I am also facing the same problem.

Hi, welcome to the community! :wave:

So what is your config?

I have the same issue I am trying to deploy to goerli

Here is my config:

import * as dotenv from "dotenv"
import { HardhatUserConfig, task } from "hardhat/config"

dotenv.config()

const config: HardhatUserConfig = {
  defaultNetwork: "hardhat",
  networks: {
    localhost: {
      chainId: 31337,
      // blockConfirmations: 1,
      allowUnlimitedContractSize: true,
    },
    hardhat: {
      chainId: 31337,
      // blockConfirmations: 1,
      allowUnlimitedContractSize: true,

    },
  },
}

export default config

I had the same issue and I figured out that the contract was too big to be deployed. Try reducing the contract size and try again, the contract should be deployed. Tried it in Ethereum Goerli

16

faced the same issue, figured out I was missing few keys here

mumbai: {
            url: "RPC_URL from metamask",
            gas: 300000000000,
            ....
        },
