Argument 1 passed to Illuminate\Database\Grammar::parameterize()

Your tags input is an array of values, so you cannot just store a php array 
into a database column.

If your tags is a varchar in your database, then try to implode the elements 
into a string:

$lesson->tags= implode(', ', $request->input('tags'));

This will store it as a comma separated list of values: programming, tech ..
so on, whatever your tags are.
