NO helpful error when generating sign url

[airyland]

Summary

I followed the doc(https://docs.phantom.app/phantom-deeplinks/provider-methods/signmessage) and did many tests to generate sign url, but all failed: unexpected error

import { Buffer } from 'buffer'
import { URLSearchParams } from 'url'
import bs58 from 'bs58'
import nacl from 'tweetnacl'

// for test
const config = {
  session: 'KDCgMju6D1HV8fWe298okbih1JEwaPrhxQTfQtSMAYJDD6wsTVhgvocPenUWUqU3grSGSs9hs9s19Y4gbkitj15cbu8BxmmMvTkW8sxAosLVvFHeokFxALtNiw4y4dA3i8XQtLFCi6KDj51eHYR7S5zFBXreFMCDwPU99ZjxDq1G9dFK8oN74QLPM7qHjNYh7SCtmzWDsZhyTU6t31BSCHPLa3L8pAcpqSK29DBvm6bc1VCU2LJTdVbPbNjn2vG',

  message: 'address: 65HZW83WNWjURRbxPQ1yVRXQhyquJv831Lui4XYj55Gi',
  timestamp: 1725413435251
}

const signMessage = async () => {
  const message = 'test message'

  const payload = {
    message: bs58.encode(Buffer.from(message)),
    session: config.session,
    display: 'utf8'
  }

  const publicKey = bs58.decode(config.dappEncryptionPublicKey)
  const secretKey = bs58.decode(config.sec)

  // Create the key pair object
  const dappKeyPair = {
    publicKey,
    secretKey
  }

  console.log(dappKeyPair)

  const sharedSecret = nacl.box.before(
    publicKey,
    secretKey
  )

  const [
    nonce,
    encryptedPayload
  ] = encryptPayload(payload, sharedSecret)

  const params = new URLSearchParams({
    dapp_encryption_public_key: bs58.encode(dappKeyPair.publicKey),
    nonce: bs58.encode(nonce),
    redirect_link: 'https://www.google.com',
    payload: bs58.encode(encryptedPayload),
    session: config.session,
    message: bs58.encode(Buffer.from(message)),
    display: 'utf8'
  })

  const url = buildUrl('signMessage', params)
  console.log('url', url)
}

const useUniversalLinks = false

const buildUrl = (path, params) =>
  `${useUniversalLinks ? 'https://phantom.app/ul/' : 'phantom://'}v1/${path}?${params.toString()}`

const encryptPayload = (payload, sharedSecret) => {
  if (!sharedSecret) throw new Error('missing shared secret')

  const nonce = nacl.randomBytes(24)

  const encryptedPayload = nacl.box.after(
    Buffer.from(JSON.stringify(payload)),
    nonce,
    sharedSecret
  )

  return [
    nonce,
    encryptedPayload
  ]
}

console.log(signMessage())

Could anyone help?

Steps to Reproduce

Just exec the code, got the url and visit it in safari, then got the error:

?errorCode=-32603&errorMessage=Unexpected+error

url example: phantom://v1/signMessage?dapp_encryption_public_key=Cfo9u5Fzs6hBCEWgtU99L5HdjTzSJAb5gJRuaDJkfL1G&nonce=2hzGV3k6P4VQHvZVKfjaojbYmsmcSMBCq&redirect_link=https%3A%2F%2Fwww.google.com&payload=3ff1VykJFtFcBoMzxRKUhBa4LMs3fhsasLxmnfr1SavRXuVoA35UTPUoGmfmfNMdYNctDkJxyw54zHM8xH1VYhMKBRzAFrWuu2mGGBG7Ro7UeGc5XGeqVGqvnfg3pqciiFt747zz5Fe8udYuCxPDnznL5e57KyTEwJZpTqpgS4iAdte6WvNdZWRueRbg293U87mP5vmUoy3HPc9zNyERjCfU69rbvqPYz7e5KQLKGmo5BhBzE8bdBMnXYyfUEjFhsDGGxY5XqYbiyHfe27gZMTbDkZbJxTamDufJPJ7n1LhqZuDze5TcMoUcgv6Ceqc3J3sZtEUjMqVGVLftNXCS7j4ZrUhVFnLhyQX6n32Lasy6ovwkQWjjnGAYWLbNUbb6P7q9ZuBbgniKP3gEmCpVSd6eAwQUHP5g42B98v7VATk2vFxTEwmpn5PX3MGfX6Vb8dTRMM&session=KDCgMju6D1HV8fWe298okbih1JEwaPrhxQTfQtSMAYJDD6wsTVhgvocPenUWUqU3grSGSs9hs9s19Y4gbkitj15cbu8BxmmMvTkW8sxAosLVvFHeokFxALtNiw4y4dA3i8XQtLFCi6KDj51eHYR7S5zFBXreFMCDwPU99ZjxDq1G9dFK8oN74QLPM7qHjNYh7SCtmzWDsZhyTU6t31BSCHPLa3L8pAcpqSK29DBvm6bc1VCU2LJTdVbPbNjn2vG&message=3CQ2BA41fzRS3uv7v&display=utf8

Is there an existing discussion for this?

Alot of errors are simply just "error when ....", they seriously need to fix this.

[airyland]

Seems they don't care.
