I am working on a React app which uses a library that has Web3 as a dependency. I had previously been able to the get the current Metamask address with the following code:
const injectedWeb3 = window.web3 || undefined;
this.state = {
web3: injectedWeb3
};
getAccount() {
const { web3 } = this.state;
if (web3.eth.accounts[0]) return web3.eth.accounts[0];
throw new Error('Your MetaMask is locked. Unlock it to continue.');
}
Then I updated that library to its latest version which changed it's Web3 dependency to Web3 1.0 . Now when I run the exact same code I get the following error:
Error: Invalid JSON RPC response: undefined
TypeError: e is not a function[Learn More]
Any thoughts as to what might be going on?
I've run into the same issue, i solved with this code:
web3.eth.getAccounts(function (err, accounts) {
if (err != null) {
console.log(err)
}
else if (accounts.length === 0) {
console.log('MetaMask is locked');
}
else {
console.log('MetaMask is unlocked');
console.log(accounts[0]);
}
});
Makbe you need also to add ethereum.enable();
. Hope this helps.
