ArgumentCountError when updating content in larvel - php

Question

In my laravel application, I'm trying to update some content using the following controller function. But every time when I try to run the following function am getting an error
public function update_tcp(Request $request, $id)
{
try{
Session::put('tcpSession', '1');
$request->merge(['gender' => 'M']);
$this->validate($request, [
'first_name_tcp2' => 'required',
'last_name_tcp2' => 'required',
'image_id' => 'image|mimes:jpeg,png,jpg,gif,svg|max:2048',
'user_id'=>'required',
'gender'=>'required',
'date_of_birth_tcp2'=>'required'
]);
//$input = $request->except('_method', '_token');
$input = $request->all();
unset($input['_token']);
unset($input['_method']);
if ($image = $request->file('image_id')) {
$destinationPath = 'propics/';
$profileImage = date('YmdHis') . "." . $image->getClientOriginalExtension();
$image->move($destinationPath, $profileImage);
$input['image_id'] = "$profileImage";
//dd($profileImage);
}else{
//unset($input['image']);
$profileImage='default-avatar.png';
$request->merge(['image_id' => 'default-avatar.png']);
}
$data = $request->input();
$tcp = TakeCarePerson::WHERE('id','=',''.$id.'');
$tcp->first_name = $data['first_name_tcp2'];
$tcp->last_name = $data['last_name_tcp2'];
$tcp->date_of_birth = $data['date_of_birth_tcp2'];
$tcp->user_id = $data['user_id'];
$tcp->image_id = $profileImage;
$tcp->gender= $data['gender'];
$tcp->update();
return redirect()->route('participants.index')
->with('success',__('texts.Take care person updated successfully.'));
} catch(Exception $e){
return back() ->with('failedTcp',__('texts.Le fichier sélectionné doit être une image.'));
}
}
This is the error,
ArgumentCountError Too few arguments to function
Illuminate\Database\Eloquent\Builder::update(), 0 passed
Where do I need to fix in order to function my update function properly?

You are not passing data to update .Instead where find by id and then call save()
$tcp = TakeCarePerson::find($id);
$tcp->first_name = $data['first_name_tcp2'];
$tcp->last_name = $data['last_name_tcp2'];
$tcp->date_of_birth = $data['date_of_birth_tcp2'];
$tcp->user_id = $data['user_id'];
$tcp->image_id = $profileImage;
$tcp->gender= $data['gender'];
$tcp->save();
or
$tcp = TakeCarePerson::where('id','=',$id)->update([
'first_name'=> $data['first_name_tcp2'],
'last_name'=>$data['last_name_tcp2'],
'date_of_birth'=>$data['date_of_birth_tcp2'],
'user_id'=>$data['user_id'],
'image_id'=>$profileImage,
'gender'=>$data['gender']
]);
