Can't load unity webgl build to facebook web hosting

Hi all,
I’m getting this message, when triyng to upload webgl build to facebook web-hosting:
“Games must reference one of our supported SDKs via our CDN.”
And the build refuses to load.
A few weeks ago nothing like that was happening, the build were uploading fine.

Could you please point me, if I’m missing something?

same here
was able to upload during last weeks, and now when we have to publish the beta of our app, this issue appeared
plz help asap

Import the last Facebook SDK from the following link Downloads - Unity SDK - Documentation - Meta for Developers then click on Build setting / player setting / resolution / Fb Template. This is the way I solved the problem, I hope it will work for you.
