I'm trying to use Web3 1.0 to call the balanceOf function on my contract. The error I get during runtime is as follows: Error: Provider not set or invalid.

The code causing the problem is as follows:

var web3 = new Web3(new Web3.providers.HttpProvider('https://mainnet.infura.io/XKEYX'));

Has anyone seen this and knows what I can do to overcome it?

Thanks
