• What is the current behavior and expected behavior?

Current behavior

It is not possible to use the polkadot.js API to set the Riot/Matrix field in the on-chain identity of an account.

Expected behavior

It should be possible to set an account's identity using only the Riot/Matrix field by passing an object with a riot field (since renamed to matrix) to api.tx.setIdentity, see the image below.

Steps to reproduce:

1. Go to https://polkadot.js.org/apps/
2. Switch to the People chain in either Polkadot or Kusama
3. Select "Fork locally"
4. In the "Developer" dropdown menu in the upper ribbon, select "</> Javascript"
5. Insert the following code

const riot = '@test:test_server.io';

# Chopsticks provided dev address, funded with DOT/KSM
const alice = '15oF4uVJwmo4TdGW7VfQxNLavjCXviqxT9S1MgbjMNHr6Sp5'

const identity = {
  matrix: { raw: riot },
}

const setIdTx = api.tx.identity.setIdentity(identity)
await setIdTx.signAndSend(alice)

# Advance a block so extrinsic takes effect
await api.rpc('dev_newBlock', { count: 1 })

const identityInfoReply = await api.query.identity.identityOf(alice)
const registrationInfo = identityInfoReply.unwrap()[0]
const identityInfo = registrationInfo.info

console.log(identityInfo.riot)

6. Execute the code, also accepting the prompt that appears to sign the transaction containing the setIdentity extrinsic
7. The output of the above console.log will be undefined, when it should be '@test:test_server.io'

P.S. changing occurences of riot above to matrix is a compile-time error, but produces the expected behavior.

I haven't tried it with "Fork locally" or alice. But I just tried with a westend account, and it worked fine.

It actually might be that there is no display name as that might be required.
