`deployContract` of the `RpcProvider` throws an error

From Consensys:

When using the “deployContract” function of the “RpcProvider” class, we always get the following error:

Error: -32602: More than 64 digits found: 76 at line 1 column 147
  at RpcProvider.eval (eval at <anonymous> (eval at <anonymous> (lockdown.umd.min.js:1:18455)), <anonymous>:70169:35)

I think the root cause is that inside the function, constructorCalldata was converted to decimal string and passed to starknet_addDeployTransaction, but they should instead be in hex string…

@jonesho & @ivpavici I came to a similar solution and have submitted a PR to fix this bug.

Hi @ivpavici

The project I am working on is currently using the OZ Cairo contracts v0.3.1. I am just using the basic Account preset:

%lang starknet

from openzeppelin.account.presets.Account import constructor

I am first instantiating a Provider based on the users config (either rpc or sequencer):

let starkNetProvider;
if (network.rpc_url) { // instantiate an RPCProvider
  starkNetProvider = new Provider({
    rpc: {
      nodeUrl: network.rpc_url
    }
  });
} else { // instantiate a SequencerProvider
  starkNetProvider = new Provider({
    sequencer: {
      baseUrl: network.base_url,
      feederGatewayUrl: network.feeder_gateway_url,
      gatewayUrl: network.gateway_url
    }
  })
}

The configuration file provides the following:

    testnet: {
      network_id: "goerli-alpha",
      rpc_url: "https://starknet-goerli.infura.io/v3/" + infuraApiKey,
      // StarkNet sequencer endpoints.
      // base_url: "https://alpha4.starknet.io",
      // feeder_gateway_url: "feeder_gateway",
      // gateway_url: "gateway",
      block_explorer_url: "https://goerli.voyager.online"
    },

Account keys are generated with the following:

const accountKeyPair = ec.genKeyPair();
const accountPublicKey = ec.getStarkKey(accountKeyPair);
const accountPrivateKey = `0x${accountKeyPair.getPrivate('hex')}`;

Contract is deployed with the following:

const callData = [
  accountPublicKey
];
const deployContractResponse = await starkNetProvider.deployContract({
  contract: compiledAccountContract,
  constructorCalldata: callData,
  addressSalt: accountPublicKey
});

This pattern works to successfully deploy an account with the sequencer provider. It fails with the following error when using the rpc provider:

/Users/david/dev/trufflesuite/boxes/starknet-box/node_modules/starknet/dist/provider/rpc.js:90
                            throw new Error("".concat(code, ": ").concat(message));
                                  ^

Thanks @janek26 I will take a look into this myself if I can make some time to do so. I have submitted a PR previously, albeit just a minor documentation fix.
