[SOLVED] What is the correct ABI format for runContractFunction

Moralis General
#1

I’m trying to call runContractFunction from https://docs.moralis.io/reference/runcontractfunction but the ABI format is making me input an ABI object.

The ABI is an array but I’m getting the error "message": "abi must contain at least 1 elements, abi must be an array, abi should not be empty":

[
  { inputs: [], stateMutability: 'nonpayable', type: 'constructor' },
  {
    anonymous: false,
    inputs: [
      {
        indexed: true,
        internalType: 'address',
        name: 'owner',
        type: 'address',
      },
      {
        indexed: true,
        internalType: 'address',
        name: 'spender',
        type: 'address',
      },
      {
        indexed: false,
        internalType: 'uint256',
        name: 'value',
        type: 'uint256',
      },
    ],
    name: 'Approval',
    type: 'event',
  },
 .......more
]

Hey there you don’t need to include the whole array of ABI in the input there, just this for the input is enough and stringify it :raised_hands:

#3

@YosephKS

Hmmm, it’s still giving me the same error.

I’m using this:

{
  inputs: [{ internalType: 'address', name: 'account', type: 'address' }],
  name: 'balanceOf',
  outputs: [{ internalType: 'uint256', name: '', type: 'uint256' }],
  stateMutability: 'view',
  type: 'function',
}

Shouldn’t that ABI object be inside an array?

#4

Ohh the one on docs has a bit of problem, but try to do it in SDKs directly it should have worked :raised_hands:

#5

it may be easier to use the swagger interface directly:
https://deep-index.moralis.io/api-docs/#/native/runContractFunction

#6

Still can’t get it to work with fetch. I’m assuming it’s just the ABI formatting.

I’m using:

const body = {
          abi: [
  {
    inputs: [{ internalType: 'address', name: 'account', type: 'address' }],
    name: 'balanceOf',
    outputs: [{ internalType: 'uint256', name: '', type: 'uint256' }],
    stateMutability: 'view',
    type: 'function',
  },
],
          params: { account: '0xDaf02BC35B0eBa38744e046eA6314FDf7CE8A113' },
        };

then I add JSON.stringify(body) to the request.

This is the request being sent:

fetch("'https://deep-index.moralis.io/api/v2/0xA6FA4fB5f76172d178d61B04b0ecd319C5d1C0aa/function?chain=polygon&function_name=balanceOf'",  {
   body: "{\"abi\":[{\"inputs\":[{\"internalType\":\"address\",\"name\":\"account\",\"type\":\"address\"}],\"name\":\"balanceOf\",\"outputs\":[{\"internalType\":\"uint256\",\"name\":\"\",\"type\":\"uint256\"}],\"stateMutability\":\"view\",\"type\":\"function\"}],\"params\":{\"account\":\"0xDaf02BC35B0eBa38744e046eA6314FDf7CE8A113\"}}"
   headers: {Accept: 'application/json', Content-Type: 'application/json', X-API-Key: 'my-web3api-key'}
   method: "POST"
})

It works with the react-moralis: Web3Api.native.runContractFunction(options) but I’m trying to migrate away from this package.

#7

when you try it in the swagger interface, you will see a working example for CURL

#8

Whatever I try with the body formatting I get "message": "Returned error: execution reverted"

I guess I’ll just keep using the web3 API for now and come back to this another day.

#9

There doesn’t seem to be a balanceOf function on that contract address (0xA6FA4fB5f76172d178d61B04b0ecd319C5d1C0aa).

What options do you use with runContractFunction from react-moralis where it works?

#10

@alex @cryptokid

I got it, I was making the request to polygon for that WETH address when I should’ve been using Mumbai.

I didn’t notice.

Thanks for checking everything!
