Feature: add getBlock and getTransaction to event details

provider.getBlock(blockNum) does not seem to work with newest blocks.

I get this error:

TypeError: Cannot read property 'author' of null
    at checkBlock (D:\walda\node_modules\ethers-providers\provider.js:152:14)
    at D:\walda\node_modules\ethers-providers\provider.js:738:20
    at process._tickCallback (internal/process/next_tick.js:109:7)

There is no problem getting past blocks however. If blockNum is the newest block’s number, then anything less than provider.getBlock(blockNum-1) works

Indeed, it helps thank you! (the bug was in my code, I tried to call this.getBlock on an event returned from getLogs 🥇 )

Certain nodes (especially INFURA, where you may be connecting to a different instance on each JSON-RPC call) do not return blocks, receipts or transactions with consistent reads.

Inside a Contract event handler, you can access this which, has a getBlock() method which will wait until the node returns the block.

contract.onfoobar = function() {
    this.getBlock().then(function(block) {
        console.log(block);
    })
}

Does that help?
