Add missing import in chain_state query

[nkostoulas]

Missing Base58Error import
Also query method was querying 'items' as well (that's how I figured out the missing import), so I've set args starting from 1

Can you give an example of what you mean by "it's querying items"? That would be something to fix in electrumx_rpc

[nkostoulas]

I mean args is a dict like:
[‘items’ ‘addr1’ ‘addr2’ ...]

And the loop in query attemps to get a hex from args[0] i.e. ‘items’.

[kyuupichan]

Well that is what needs to be understood and fixed; ignoring an argument is not the answer. I'm not clear on why this worked fine for me

[kyuupichan]

This works fine for me:

$ ./electrumx_rpc query --limit 1 76a91462e907b15cbf27d5425399ebf6f0fb50ebb88f1888ac

Also with an address:

$ ./electrumx_rpc query --limit 2 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa

The bug is simply the missing import:

$ ./electrumx_rpc query --limit 2 1A1zP1eP5QGefi2D
error making request: RPCError(-32603, 'internal server error')

when neither a script hash nor an address is passed. So I don't understand your point about "items"

[nkostoulas]

You're right I misinterpreted the help instructions. I'll remove that change.

[kyuupichan]

I fixed this in a3afab8

If you still have a problem with "items" can you open an issue. Thanks
