Unable to use Facebook SDK for Conversion API requests

[Arnold Gálovics]

Which SDK version are you using?

15.0.0

What's the issue?

The SDK cannot be used to send requests to the Conversion API due to a bug in the response processing where the code tries to upcast an APINode instance to an AdsPixel object.
The fix is already in place in the main branch yet there's no bugfix release yet.
The commit is this: 4cba80f

Since it's already fixed, I propose to create a bugfix release ASAP, otherwise the SDK is unusable to report pixel events.

Steps/Sample code to reproduce the issue

Send a regular API request to CAPI

Observed Results:

Exception occurs:

java.lang.ClassCastException: class com.facebook.ads.sdk.APINode cannot be cast to class com.facebook.ads.sdk.AdsPixel (com.facebook.ads.sdk.APINode and com.facebook.ads.sdk.AdsPixel are in unnamed module of loader 'app')
	at com.facebook.ads.sdk.serverside.EventRequest.sendToCAPIEndpoint(EventRequest.java:434) ~[facebook-java-business-sdk-15.0.0.jar:na]
	at com.facebook.ads.sdk.serverside.EventRequest.execute(EventRequest.java:401) ~[facebook-java-business-sdk-15.0.0.jar:na]

Expected Results:

Request goes to CAPI successfully.
