    {

      $bond = Bond::create([
          'investment' => request('investment'),
          'investment_name' => request('investment_name'),
          'i_id' => request('i_id'),
          'price' => request('price'),
          'p_goal' => request('p_goal'),

Answer 1

The request('investment') is nullable, however your field investment in bonds cannot be nullable. So you can use validator to check the fields.Or set the default value in this field.

Use validator:

try to use validator like this:

public function store(Request $request)
    {
      $this->validate($request, [
          'investment' => 'required',
          ...
      ]);


      $bond = Bond::create([
          ....
}

Set default value:

$bond = Bond::create([
   'investment' => $request->input('invenstment', 'your_default_value');
   ...
]);

Change the field to nullable:

$table->string('investment')->nullable();
