cannot add foreign key constraint laravel

1$table->foreignId('user_id')
2      ->constrained("users") <- // You don't need to specify table if it matched laravel naming conventions.
3      ->onUpdate('cascade')
4      ->onDelete('cascade');

1Add it in two steps, and its good to make it unsigned too:
2public function up()
3{
4    Schema::create('priorities', function($table) {
5        $table->increments('id', true);
6        $table->integer('user_id')->unsigned();
7        $table->foreign('user_id')->references('id')->on('users');
8        $table->string('priority_name');
9        $table->smallInteger('rank');
10        $table->text('class');
11        $table->timestamps('timecreated');
12    });
13}
14
15if still same error try removing unsigned() from the above code
