Internally the request event is effectively deserialized using: let event = serde_json::from_slice<T>(&body) where `T` is the type used for the handler's event type. If this is a String then Serde will fail to deserialize the JSON input (it won't ever just be a string). Handler's should use a structured type for the event that Serde will be able to deserialize the incoming JSON event data into, so this updates the examples to use serde_json::Value.

Description of changes:
This is a documentation (and examples) tweak to consider that lambda handlers need to use a structured type for their event data since Serde will try and deserialize a JSON document into that type and that won't work with a String type which the current examples use.
