Deploy problems with npx hardhat run scripts/deploy.ts

[luislucena16]

hi @excaliborr following the instructions of the repo I have a problem in step number 9 of here when I run the command to deploy I get this error:

Details: fetch is not defined
Version: [email protected]

have you seen it before? thanks in advance!

[excaliborr]

How are you getting this error can you share some code snippets? You are running the example repo right? We dont use viem or fetch in there by default if I remember correctly

[luislucena16]

@excaliborr yes, I am running the example repository, then the error could be in relation to pimlico, I also get this as part of the error:

  details: 'fetch is not defined',
  docsPath: undefined,
  metaMessages: [
    'URL: https://api.pimlico.io/v1/mumbai/rpc?apikey=my_key',
    'Request body: {"method":"eth_chainId","params":[]}'
  ],
  shortMessage: 'HTTP request failed.',
  version: '[email protected]',
  body: { method: 'eth_chainId', params: [] },
  headers: undefined,
  status: undefined,
  url: 'https://api.pimlico.io/v1/mumbai/rpc?apikey=my_key'

I am using Pimlico's bundler and paymaster

[excaliborr]

the my_key was a placeholder in the readme, you need to fill this in with the pimlico API key that you will need to get on your own

[luislucena16]

that my_key was added by me for the example here in github, I'm using my apiKey correctly

[excaliborr]

oh oops mb! Have you installed the dependencies in both the account-abstraction repo and the example repo, and ran yarn link to link them? The fetch is not defined sounds like a dependency error, have you modified any code from the example repo or you just cloned and ran it?

[luislucena16]

yes, I have installed the dependencies as in the instructions and all the commands as well, up to step (9) I got there, the only thing I modified of course was the hardhat.config.ts, I modified the code you indicate with Example

[excaliborr]

What node version are you using, can you try with node 20+

[luislucena16]

@excaliborr nice!! it was that, i updated my node version and it worked fine, now with the next pass which is to run the integration tests it breaks

• error messages:

 Should send a transaction:
     Error: could not decode result data (value="0x", info={ "method": "balanceOf", "signature": "balanceOf(address)" }, code=BAD_DATA, version=6.9.0)

Should transfer tokens from the smart account:
     Error: could not decode result data (value="0x", info={ "method": "balanceOf", "signature": "balanceOf(address)" }, code=BAD_DATA, version=6.9.0)

[excaliborr]

Our integration test suite uses testnet contracts on ethereum sepolia, if you are using a different network that is probably why as the contracts we test dont exist there

[luislucena16]

of course, that's right! now it's working for me!

[luislucena16]

have you done any test with biconomy? i was trying from sepolia with the paymaster and bundlr from them but it doesn't recognise it:

Error: Unknown paymaster type

[excaliborr]

Yes we currently do not support biconomy in this version of the plugin, here is a list of paymasters we support: https://github.com/defi-wonderland/hardhat-account-abstraction?tab=readme-ov-file#supported-paymaster-types

If you would like to attempt to add support for this paymaster you are welcome to give it a go!

[luislucena16]

good, I will try!
