provider.getBlock does not output all the block details

See original GitHub issue

I am working on a block explorer project with ethers.js, experiencing that some data is not being outputted (specifically transaction and state roots). I tried the same with web3.js and could see these details.

getBlock from web3.js (https://web3js.readthedocs.io/en/v1.2.4/web3-eth.html#id51)

The ethers.js getBlock gives the following output

I also saw #276 which is closed, so I created a new one.

Just figured out a way to do this with ethers js: const block = await provider.send('eth_getBlockByNumber', [ethers.utils.bigNumberify(i)._hex, true]);

Thank you @zemse this worked well.

const fullBlock = await provider.send(
    'eth_getBlockByNumber',
    [ethers.utils.hexValue(blockNumber), true]
)
