Missing mraid.open unity playable ads

Hello,
I am trying to make a playable ads for unity ads.
While trying to test if Tiny can do this. I hit a wall.
I get an errors while uploading to "Creative packs":

Creative pack validation failed:

Your responsive playable is missing mraid.open()
Your responsive playable is missing a store URL or the store URL is invalid

I am using 0.31 example tiny2d-wasm on PC.

Any help will be greatly appreciated.
