Facebook Playable Ads preview not work

Hi all!

I have some problems with preview of my playable ads for Facebook.
On Facebook Playable Ads Preview tool I can see only some code instead my playable ads.
Screenshot: https://take.ms/CRSp5

What I use: TypeScript, Babel, Webpack, Phaser, and TerserPlugin for minify.
I tried 3.21, 3.23, and CE 2.15 version of Phaser.
All minified code was added to index.html like inline.

I tried some examples on Phaser 3 version , and… Facebook playable ads preview tool can’t display all of them.

After testing with Phaser 3 version I tried to create simple example with Phaser CE 2.15 version.

Results of tests:

  • Phaser 3:
    – ironSource can display playable ads [OK]
    – appLovin can display playable ads [OK]
    – facebook can’t display playable ads [NOT OK]
  • Phaser CE 2.15:
    – ironSource can display playable ads [OK]
    – appLovin can display playable ads [OK]
    – facebook can display playable ads [OK]

So… maybe someone knows about this issues and can help me?

Thx!
