@prasannakumark did you solve this issue? I'm having the same problem

[prasannakumark]

@brandall76 Yes its solved. we have to send .setPlayloadOffsetInMilliseconds(offset) as well. FYI, https://forums.developer.amazon.com/questions/105694/playbackfinished-event-response-is-bad-request-alw.html#answer-106368
