Get a little mini-torch (like the kind you use in the kitchen to brûlée a dessert, which is a totally normal thing that everyone does). While the resin is still liquid, blast that spot quickly with the torch. The bubbles should all pop. Practise on some things you don't care about first - if you flame too long you can discolour the resin. You can also use a toothpick to pop the larger bubbles and sweep the smaller bubbles to the edge, but this can be very fiddly.

I'm also finding that the insects often have trapped air in them. And the torch stops working after the resin forms a skin. I'm wondering if I should build a vacuum chamber. Maybe thatd pull the bubbles out

Should work fine if you can get a good seal. In the lab we use Vaseline on all the seals to help with that. Make sure your Tupperware is stiff, or the lid will buckle and break the seal.
