Same issue on latest with @aws-amplify/analytics v4.0.5

Editing the value to be TIMESTAMP in the provider solves this issue. This begs the question: does the provider just need changed to TIMESTAMP instead of timestamp?

Here is the problematic block of code. The timestamp property is not allowed in properties. Could you please rename timestamp?
