Command Given : web3.eth.personal.unlockAccount(web3.eth.defaultAccount, "user").then(() => TokenDeployTransaction.estimateGas()).then(gas => TokenDeployTransaction.send({gasLimit: 5000000, from: web3.eth.defaultAccount})).then(contract => { console.log("Address of new contract: " + contract.options.address); TokenContract = contract; }).catch(err => console.log(err)); Error: Promise { , domain: Domain { domain: null, _events: [Object: null prototype] { removeListener: [Function: updateExceptionCapture], newListener: [Function: updateExceptionCapture], error: [Function: debugDomainError] }, _eventsCount: 3, _maxListeners: undefined, members: [], [Symbol(kWeak)]: WeakReference {} } }

I have avoided the estimate gas command and given a new command. The new command is web3.eth.personal.unlockAccount(web3.eth.defaultAccount, "user").then(gas => TokenDeployTransaction.send({gasLimit: 500000000, from: web3.eth.defaultAccount})).then(contract => { console.log("Address of new contract: " + contract.options.address); TokenContract = contract; }).catch(err => console.log(err)); Error is Promise { , domain: Domain { domain: null, _events: [Object: null prototype] { removeListener: [Function: updateExceptionCapture], newListener: [Function: updateExceptionCapture], error: [Function: debugDomainError] }, _eventsCount: 3, _maxListeners: undefined, members: [], [Symbol(kWeak)]: WeakReference {} } }

Error: The contract code couldn't be stored, please check your gas limit. at Object.callback (/home/krishnan/pwasm-tutorial/node_modules/web3-core-method/src/index.js:333:46) at sendTxCallback (/home/krishnan/pwasm-tutorial/node_modules/web3-core-method/src/index.js:484:29) at /home/krishnan/pwasm-tutorial/node_modules/web3-core-requestmanager/src/index.js:147:9 at XMLHttpRequest.request.onreadystatechange (/home/krishnan/pwasm-tutorial/node_modules/web3-providers-http/src/index.js:96:13) at XMLHttpRequestEventTarget.dispatchEvent (/home/krishnan/pwasm-tutorial/node_modules/xhr2-cookies/dist/xml-http-request-event-target.js:34:22) at XMLHttpRequest._setReadyState (/home/krishnan/pwasm-tutorial/node_modules/xhr2-cookies/dist/xml-http-request.js:208:14) at XMLHttpRequest._onHttpResponseEnd (/home/krishnan/pwasm-tutorial/node_modules/xhr2-cookies/dist/xml-http-request.js:318:14) at IncomingMessage.

Even changing the gaslimit to 8000000 didnt solve the issue.
