Analytical events failed to reach Appsflyer and Amplitude

Hello!
I have integrated Adapty with AppsFlyer and Amplitude exactly as it is written in the documentation and rechecked everything.
But I am still getting errors in Adapty:

One or more analytical events failed to reach AppsFlyer (Android);
One or more analytical events failed to reach Amplitude.

Could you please advise me how to cope with this issue?
