function eth_workaround_eth_coinbase($val)

[Cryt1c]

Hi @digitaldonkey ,

thanks for providing this interface and also the drupal/ethereum module!
I would like to contribute to this project too.
Currently I try to get the dev branch running on my environment but I have a problem, when I use the INFURA net because eth_coinbase is not supported by them.
I have found these workaround:

{
    // WORKAROUND: Catch a "405 Method Not Allowed'.
    if (isset($val['error']) && $val['error'] && $val['code'] == 405) {
        return '0x0000000000000000000000000000000000000000';
    } else {
        return $val;
    }
}

But as I see it they are not used at the moment, which breaks the drupal/ethereum module because ethereum-php throws an Exception which is not caught (Expected EthD20 at eth_coinbase (), couldn not be decoded. Value was: Array).
Where should this workaround be used? Can I help you with this? Would be happy to create a PR if you could point me into the right direction.

Thanks for your work!

The workarounds should be called in

ethereum-php/src/Ethereum.php

Lines 195 to 198 in aef4551

	$functionName = 'eth_workaround_' . $method;
	if (function_exists($functionName)) {
	$value = call_user_func($functionName, $value);
	}

If this is not happening https://github.com/digitaldonkey/ethereum-php/blob/dev/src/helpers/ethereum-client-workaround-helpers.php is not included correctly, which would be a bug sneaked in during refactoring.

ethereum-php throws an Exception which is not caught (Expected EthD20 at eth_coinbase (), couldn not be decoded. Value was: Array).

Array values are not yet implemented in the library.

I assume the helper file is not included.

I would like to contribute to this project too.
You are very welcome. PM me if you want to schedule a call, so I can tell you what I'm working on currently.

Seems src/helpers/ethereum-client-workaround-helpers.php is not loaded.
