Error : Call to a member function update() on null
```
The error Call to a member function update() on null means that Post::find($id) returned null. This may be because $id is itself null, or the value of $id does not exist in the id column of the posts table.

You have to check the $id value should not be null and after that you have to check the record with this id (value) exists in the table. It will return 1 if everything is ok else it will return Call to a member function update() on null.
