Cannot sign data with DRep PubKey hash

[reeshavacharya]

Steps to reproduce

• enable lace cip95 wallet in the browser console

lace = await window.cardano.lace.enable({extensions: [{cip: 95,},],})

• get your drep Public Key

await lace.cip95.getPubDRepKey()

• obtain the dRep Pub Key Hash

import { blake2bHex } from "blakejs";
const drepPubKeyHash = blake2bHex(Buffer.from(dRepPubKey, "hex"), undefined, 28);

• use the pubKey hash to sign the data

await lace.signData('02e2c71f20b18de66fda797c42549d7318a4e6345aefabf4805a5df8', '6869')

There must be a cip95 instance to sign data.
eg: await lace.cip95.signData('02e2c71f20b18de66fda797c42549d7318a4e6345aefabf4805a5df8', '6869')

Expected

• wallet should be able to sign the data with dRep public key as wallets like eternl and yoroi are able to

Observed

• ERROR : "Invalid argument 'data': Base address data length should be 57 bytes long."

Thanks for the report @reeshavacharya. Is this directly impacting a particular DApp or did you discover this during testing of a library or similar? This will help determine the priority for us to fix, but we'll also happily accept a contribution too.
