Auth0lock, auth params being transformed

Hi, I am currently implementing auth with auth0lock on a project. I have an action on login that is sending data to an internal tool, and the tool wants some query parameters such as: userId, but when I pass these values as params in for auth, they are being transformed to user_id. Is there any way to prevent this transformation?

const lock = new Auth0Lock(
    autoclose: true,
    rememberLastLogin: true,
    autoParseHash: true,
    auth: {
      redirect: false,
      redirectUrl: `${window.location.origin}/callback`,
      responseType: 'token id_token',
      params: {
    allowForgotPassword: true,
    usernameStyle: 'email',
    closable: false,

The above on login would have the following query paramter: user_id=, instead of the passed userId.
