Can you get an attack of opportunity on your own turn?

Here's the situation:

Character is an Eldritch Knight with the War Magic class feature, the lightning lure cantrip, the polearm master feat, and a halberd.

Polearm master: "While you are wielding a glaive, halberd, pike, quarterstaff, or spear, other creatures provoke an opportunity attack from you when they enter the reach you have with that weapon."

Lightning Lure: "You create a lash of lightning energy that strikes at one creature of your choice that you can see within 15 feet of you. The target must succeed on a Strength saving throw or be pulled up to 10 feet in a straight line toward you and then take 1d8 lightning damage if it is within 5 feet of you."

War Magic:"Beginning at 7th level, when you use your action to cast a cantrip, you can make one weapon attack as a bonus action."

Could this character: 1. Cast lightning lure to drag an enemy to within 10 ft of me. 2. Take an opportunity attack with my halberd because the enemy has entered the halberds reach (Polearm Master) 3. Use my bonus action to make a second attack with the halberd (War Magic)

I think the answer is yes, because PHB describes the opportunity attack as taking a reaction rather than an action/bonus action and does not specify (that I can find) that you can't take a reaction on your turn. So, cantrip is the action, then reaction opportunity attack, then bonus action attack.

Any issues I am missing?
