Fail to launch cloud-function-aws sample behind Amazon API Gateway

[masatotoro]

I would like to launch cloud-function-aws sample behind Amazon API Gateway. But when I make an API call, I get the following error:

Started

Please give me some advice on how to solve this problem. Should I use Jackson's ObjectMapper to set the Json of the String as the return value of the Function?

I would like to suggest changing "function-aws" to "cloud-function-aws". It couldn't work without this change.

@masatotoro I did the name changes, could you please try again? (you may have to use Spring Boot 2.4.1 due to #446).

Since no feedback I assume it is fixed, please comment if that's not the case.
