executed command = npx hardhat run --network mumbai .\scripts\prepare-upgrade-ENFT.script.js
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.

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?

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:

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
