Based on Michael Czechowski I edited my answer to make this answer better, The main problem is inside your routes:
You have to add the id inside your route parameters either. Your update() function needs two parameters, first the form parameters from the formular and second the $id of the edited log entry.
The second problem is , the form method field is 'patch' and your route method is 'put'.
The difference between 'patch' and 'put' is:
put: gets the data and update the row and makes a new row in the database from the data that you want to update.
patch: just updates the row and it does not make a new row.
so if you want to just update the old row change the route method to patch.
or if you really want to put the data, just change the put method field in your form.
simply by :
Remember, the form's and the route's methods must be same. If the form's method is put, the route method must be put; and vice-versa.
