Creating default object from empty value on update Laravel - php

Question

I realize this question has been asked several times on this forum, but none of the solutions given has resolved my particular issue.
I get the above error when trying to update my DB.
Here is a snippet of my code
I have tried adding findorfail on my request by id
$service=Service::findorfail($request->input('id'));
This returns a 404 page.
ServiceController.php
public function updateService(Request $request){
// return $request->all();
$this->validate($request, ['serviceTitle'=> 'required',
'serviceSubTitle'=> 'required',
'description'=> 'required',
'slug' => 'required|min:3|max:255|unique:services',
'serviceImage'=>'image|nullable|max:1999']);
$service=Service::find($request->input('id'));
$service->title =$request->input('serviceTitle');
$service->sub_title =$request->input('serviceSubTitle');
$service->slug =$request->input('slug');
$service->description =$request->input('description');
if($request->hasFile('serviceImage')) {
//1 : get filename with ext
$fileNameWithExt = $request->file('serviceImage')->getClientOriginalName();
//2 : get just file name
$fileName = pathinfo($fileNameWithExt, PATHINFO_FILENAME);
//3 : get just extension
$extension = $request->file('serviceImage')->getClientOriginalExtension();
//4: filename to store
$fileNameToStore = $fileName.'_'.time().'.'.$extension;
//upload image
$path =$request->file('serviceImage')->storeAs('public/serviceImage', $fileNameToStore);
$old_image =Service::find($request->input('id'));
if($old_image!='noimage.jpg') {
Storage::delete('public/serviceImage/'.$old_image->image);
}
$service->image =$fileNameToStore;
}
$service->update();
return redirect('/services')->with('status', 'The '.$service->title.' Service has been updated successfully');
}
The error log tells me the error is on this specific line:
$service->title =$request->input('serviceTitle');
Thank you for time and assistance.
