I'm trying to deploy an EOS Smart Contract using eosjs.
I referred the code from https://eosio.github.io/eosjs/latest/how-to-guides/how-to-deploy-a-smart-contract
const wasmFilePath = './hello.wasm'
const abiFilePath = './hello.abi'
const fs = require('fs')
const { Api, JsonRpc, Serialize } = require('eosjs');
const { JsSignatureProvider } = require('eosjs/dist/eosjs-jssig'); // development only
const fetch = require('node-fetch'); //node only
const { TextDecoder, TextEncoder } = require('util'); //node only
let privateKey1 = '5J***********'
const privateKeys = [privateKey1];
const signatureProvider = new JsSignatureProvider(privateKeys);
const rpc = new JsonRpc('https://jungle2.cryptolions.io:443', { fetch }); //required to read blockchain state
const api = new Api({ rpc, signatureProvider, textDecoder: new TextDecoder(), textEncoder: new TextEncoder() });
const wasmHexString = fs.readFileSync(wasmFilePath).toString('hex')
const buffer = new Serialize.SerialBuffer({
textEncoder: api.textEncoder,
textDecoder: api.textDecoder,
})
let abiJSON = JSON.parse(fs.readFileSync(abiFilePath, 'utf8'))
const abiDefinitions = api.abiTypes.get('abi_def')
abiJSON = abiDefinitions.fields.reduce(
(acc, { name: fieldName }) =>
Object.assign(acc, { [fieldName]: acc[fieldName] || [] }),
abiJSON
)
abiDefinitions.serialize(buffer, abiJSON)
let serializedAbiHexString = Buffer.from(buffer.asUint8Array()).toString('hex')
deployContract();
async function deployContract(){
try{
const wasmFilePath = './hello.wasm'
const abiFilePath = './hello.abi'
const fs = require('fs')
const { Api, JsonRpc, Serialize } = require('eosjs');
const { JsSignatureProvider } = require('eosjs/dist/eosjs-jssig'); // development only
const fetch = require('node-fetch'); //node only
const { TextDecoder, TextEncoder } = require('util'); //node only
let privateKey1 = '5J***********'
const privateKeys = [privateKey1];
const signatureProvider = new JsSignatureProvider(privateKeys);
const rpc = new JsonRpc('https://jungle2.cryptolions.io:443', { fetch }); //required to read blockchain state
const api = new Api({ rpc, signatureProvider, textDecoder: new TextDecoder(), textEncoder: new TextEncoder() });
const wasmHexString = fs.readFileSync(wasmFilePath).toString('hex')
const buffer = new Serialize.SerialBuffer({
textEncoder: api.textEncoder,
textDecoder: api.textDecoder,
})
let abiJSON = JSON.parse(fs.readFileSync(abiFilePath, 'utf8'))
const abiDefinitions = api.abiTypes.get('abi_def')
abiJSON = abiDefinitions.fields.reduce(
(acc, { name: fieldName }) =>
Object.assign(acc, { [fieldName]: acc[fieldName] || [] }),
abiJSON
)
abiDefinitions.serialize(buffer, abiJSON)
let serializedAbiHexString = Buffer.from(buffer.asUint8Array()).toString('hex')
deployContract();
async function deployContract(){
try{
await api.transact(
{
actions: [
{
account: 'eosio',
name: 'setcode',
authorization: [
{
actor: user_name,
permission: 'active',
},
],
data: {
account: user_name,
code: wasmHexString,
},
},
{
account: 'eosio',
name: 'setabi',
authorization: [
{

permission: 'active',
},
],
data: {
account: user_name,
abi: serializedAbiHexString,
},
},
],
},
{
blocksBehind: 3,
expireSeconds: 30,
}
)
}
catch(e){
console.log(e)
}
};
};
I'm getting the following error:

Add vmtype and vmversion in data field of setcode.
