// Laravel can't determine the plural form of the word you used for your table name.

// Just specify your table in the model as such:

class Cotizacion extends Model{
    public $table = "your table name";

SQLSTATE[42S02] lumen

You need to define the table name in model as shown below.
class User extends Model
{
    //
    public $table = "products";
}

class Cotizacion extends Model{
    public $table = "cotizacion";

It seems Laravel is trying to use category_posts table (because of many-to-many relationship). But you don't have this table, because you've created category_post table. Change name of the table to category_posts.
