Firebase database: invalid token in path
<p>my question is this, I´m getting this error:
    <code>com.google.firebase.database.DatabaseException: Firebase Database error: Invalid token in path</code>, when I update a User´s node which from this code:</p>

<pre><code>Map&lt;String, Object&gt; userUpdate = new HashMap&lt;&gt;();
        userUpdate.put("/" + Constants.Users + "/" + userEncEmail + "/profile_data/age", age);
        userUpdate.put("/" + Constants.Users + "/" + userEncEmail + "/profile_data/email", userEmail);
        userUpdate.put("/" + Constants.Users + "/" + userEncEmail + "/profile_data/gender", gender);
        userUpdate.put("/" + Constants.Users + "/" + userEncEmail + "/profile_data/name", userName);
        userUpdate.put("/" + Constants.Users + "/" + userEncEmail + "/profile_data/photo", "");
        userUpdate.put("/" + Constants.Users + "/" + userEncEmail + "/profile_data/video", "");

        userUpdate.put("/" + Constants.Users + "/" + userEncEmail + "/chat_data/osPlayerID", "");
        userUpdate.put("/" + Constants.Users + "/" + userEncEmail + "/chat_data/name", userName);
        userUpdate.put("/" + Constants.Users + "/" + userEncEmail + "/chat_data/photo", "");
        userUpdate.put("/" + Constants.Users + "/" + userEncEmail + "/chat_data/video", "");

        userUpdate.put("/" + Constants.Users + "/" + userEncEmail + "/status", false);//Set false by default

        FirebaseDatabase.getInstance().getReference().updateChildren(userUpdate).addOnCompleteListener(new OnCompleteListener&lt;Void&gt;() {
            @Override
            public void onComplete(@NonNull Task&lt;Void&gt; task) {
</code></pre>

<p>The rules from Firebase Database to this specific node are: true for write and read.</p>

<p>The Json expected is: </p>

<pre><code>{
  $UserEMail: {
     chat_data: {
       name: "",
       osPlayerID: "",
       photo: "",
       video: ""
     },
     profile_data: {
      age: (int),
      email: "";
      gender: (int),
      name: "",
      photo: "",
      video: ""
    },
    status: (boolean)
  }
}
</code></pre>
