Issue parsing APIGateway Event

[idelfonsog2]

Expected behavior

Expected my lambda to return a APIGatewayV2Response along with my body

Actual behavior

Found the following in the CloudWatch Logs

2022-04-25T15:40:54+0000 warning Lambda : lifecycleIteration=1 lambda handler returned an error: requestDecoding(Swift.DecodingError.keyNotFound(CodingKeys(stringValue: "version", intValue: nil), Swift.DecodingError.Context(codingPath: [], debugDescription: "No value associated with key CodingKeys(stringValue: \"version\", intValue: nil) (\"version\").", underlyingError: nil)))

Steps to reproduce

1. Use the Deployment Lambda found in the Examples dir and deployed to AWS using APIGateway with a Lambda_PROXY
2. make an HTTP call to your APIGateway
3. Observe the errors in the CloudWatch Log

If possible, minimal yet complete reproducer code (or URL to code)
