Unable to insert id of user to another table laravel 8 livewire - laravel-8

Question

I am unable to store user id of another user on my db. I have a messages table, where from_id,t_id and user_id are the foreign key of table users. I have models defined properly as well. The issue I am having is:
can't insert the user_id.
I can save everything else. when i do dd $this->id it shows the corret user id but when it comes to save them i can't.
I tried doing explode and it stopped showing those random values. it now gets the id however in below format: [{"id":3}]
: Invalid text representation: 7 ERROR: invalid input syntax for type bigint: "[{"id":3}]"
As you can see it's getting the user id when i get the values from authenticated user which is obvious.
My code :
public $messages, $sender;
public $users;
public $avatar;
protected $destination = '';
public $messageText;
public function mount($id)
{
$this->id = $id;
$this->avatar = DB::table('users')
->join('messages', 'users.id', '=', 'messages.user_id')
->select('users.id')
->where('users.id', '=', $this->id)->distinct()->get();
$this->destination = DB::table('users')
->join('messages', 'users.id', '=', 'messages.user_id')
->select('users.id')
->where('users.id', '=', $this->id)->first();
$this->users =
Message::latest()
->take(5)
->get()
->sortBy('id');
$this->messages = DB::table('users')
->join('messages', 'users.id', '=', 'messages.user_id')
->select('users.name', 'users.id', 'messages.message', 'messages.created_at')
->where('users.id', '=', $this->id)
->get();
// SELECT * FROM users AS u INNER JOIN messages AS m ON u.ID IN (m.senderID, m.recipientID) WHERE u.ID <> $userID GROUP BY u.ID ORDER BY m.sentAt DESC
}
public function render()
{
// $name = explode(' ', $this->avatar);
// dd($name);
return view(
'livewire.show',
[
'avatar' => $this->avatar,
'messages' => $this->messages,
'users' => $this->users,
]
)->layout('layouts.app');
}
public function sendMessage()
{
$name = explode(' ', $this->avatar);
// $this->validate(['messageText' => "required"]);
$message = new Message();
$message->from_id = Auth::user()->id;
$message->user_id = Auth::user()->id;
$message->to_id = $name[0]; // [{"id":3}]
$message->message = $this->messageText;
// dd($message);
$message->save();
$this->reset('messageText');
}
