api.derive.democracy.proposals() failed to get proposals

[JayJay1024]

const provider = new WsProvider('wss://darwinia-crab.api.onfinality.io/public-ws');

const proposals = await api.query.democracy?.publicProps();

proposals.forEach(([, ,proposer]) => {
  console.log(proposer.isEmpty, proposer.toHuman());
});

the proposer is not empty, but proposer.isEmpty is true , what could be the root cause

I think they shield the 0x0...00 address intentionally.

I think they shield the 0x0...01 address intentionally.

Yes, but to correct, because the proposer here is 0x00000...000.

In the above screenshot the proposer should be 5C4hrfjw9DjXZTzV3MwzrrAr9P1MJhSrvWGWqi1eSuyUpnhM and 5C4hrfjw9DjXZTzV3MwzrrAr9P1MJhSrvWGWqi1eSuyUpnhM

5C4hrfjw9DjXZTzV3MwzrrAr9P1MJhSrvWGWqi1eSuyUpnhM is all-empty, i.e. 0x0000...0000

You can check in the JS dev console on apps,

console.log(hashing.decodeAddress('5C4hrfjw9DjXZTzV3MwzrrAr9P1MJhSrvWGWqi1eSuyUpnhM'))

The 0x00...01 is the hash component from (u32, Hash, AccountId)

@jacogr Maybe we should not shield 0x0...00 here, because the private key of 0x0...00 is known to public, anyone can reveal its keys and send extrinsic as 0x0...00.

Shielding this address in UI will prevent the governance participants from discovering these malicious proposals earlier.

But this will also make the 'bug' more public.

But this will also make the 'bug' more public.

It is already public, and it is from crypto, not something can be hided/fixed in UI. We should have more people know this instead of only being known by malicious, making information asymmetry more severe.

Closing, nothing to be done API-wise.
