Cannot customize the error message on password change with custom database connections

Help

I’m using custom database connections with “Change Password” database action script like this:

function changePassword(email, newPassword, callback) {
  // initialize my client ...
  
  someClient.changePassword(someParams)
    .then((res) => {
      // success!
      callback(null, true);
    })
    .catch((e) => {
      // failed!
      callback(new Error("Something wrong!"));
    });
}

When the password change fails for some reason (ex: too weak password), we want to show the custom error message “Something wrong!”, but got “There was an error processing the password reset.” instead.
How can we achieve this?
