transactions field is null. I think it should be an array (Don't know should it be filled with transactions or not)

https://github.com/etclabscore/core-geth/blob/master/internal/ethapi/api.go#L691
here inclTx param should be true?

Thanks for this!

Here's a corresponding call at ethereum/go-ethereum v1.9.24 for reference; transactions is actually omitted entirely (different from getBlock_ methods).

And although the docs are not a perfect source of reference, I'm including a screenshot here to show the Note indicating -- as I'm interpreting it -- that transactions should in fact be omitted.

https://eth.wiki/json-rpc/API (I'd provide a deep link but that feature appears to be broken.)

Per the above auto-citation, I've included a fix for this in the PR resolving the other nullable fields issue (#332).
