How to fix Laravel 7 redirect causing 405 error?

What I am trying to do is after a record has been deleted, redirect back to a certain page with a success message. The error that I am getting is that the redirect is causing a "405 method not allowed error". If I remove the redirect the delete works fine.

My Delete Method

public function destroy($id){
    $customer = Customer::find($id);
    $customer->delete();
    return redirect()->route('customers.index')->with('success','Customer deleted');
}

Other Redirect Methods I've Tried

return redirect()->action('CustomerController@index')->with('success', 'Customer deleted');
redirect('pages.customers.index')->with('success', 'Customer deleted');
return redirect()->to('/customers')->with('success', 'Customer deleted')->send();

Route Configuration

Route::resource('customers', 'CustomerController');

My Index Method

public function index()
{
    $customers = Customer::all();
    return view('pages.customers.index', compact('customers'));
}

From what I've read on other posts, the wrong method is being used when redirecting, is there a way I can specify which method to use?
