Creating default object from empty value during update with eloquent relationship in laravel

Question

I am trying to update 'employee' and 'employee_details' in which I used one to one relationship. During the update, I am getting this error exactly in $employeeDetail->card_no = $request->card_no, in employeeDetail and I searched and tried to implement the possible solutions but still getting this error. Would someone help me to solve this problem, please?

EmployeeController.php

public function update(Request $request, $id)
{
    $employee = Employee::find($id);
    $employee->card_no = $request->card_no;
    $employee->name = $request->name;
    $employee->father_name = $request->father_name;
    $employee->mother_name = $request->mother_name;
    $employee->spouse_name = $request->spouse_name;
    $employee->permanent_add = $request->permanent_add;
    $employee->present_add = $request->present_add;
    $employee->area = $request->area;
    $employee->dob = Carbon::parse($request->dob)->format('Y-m-d');
    $employee->blood_group = $request->blood_group;
    $employee->nid_number = $request->nid_number;
    $employee->mobile = $request->mobile;
    $employee->reference_name = $request->reference_name;
    $employee->reference_nid = $request->reference_nid;
    $employee->reference_mobile = $request->reference_mobile;
    $employee->reference_add = $request->reference_add;

    if (! $request->photo == '') {
        $employee->photo = $request->photo;
        if ($file = $request->file('photo')) {
            $extension = $file->getClientOriginalExtension() ?: 'png';
            $folderName = '/uploads/employees/photo';
            $destinationPath = public_path() . $folderName;
            $safeName = str_random(10) . '.' . $extension;
            $file->move($destinationPath, $safeName);
            //delete old photo if exists
            if (File::exists(public_path() . $folderName . $employee->photo)) {
