Trigger AWS Lambda function with a string payload
I have a function on AWS Lambda written in Java that can currently only accept text event data, not JSON.
Whenever I go in the test console, if my test event has a payload of "", the function runs, however if it's a json, it does not.
If I run it with any of the triggers, such as S3, CloudWatch Events or with a API Gateway, they always send out a json.
Is there by any chance a possibility to run those triggers and make them send a string payload instead of a json payload?

To accept JSON as input, you need to update your RequestHandler<JSONObject, String> and
public class Hello implements RequestHandler<JSONObject, String>
public String myHandler(JSONObject jsonObj, Context context)
// add your processing logic.
return "done!";
Alternatively, you can define a POJO with the attributes of your json payload like
class Payload
//fields
//setter & getter
And use this Payload type in your RequestHandler as
public class Hello implements RequestHandler<Payload, String>
public String myHandler(Payload payload, Context context)
// add your processing logic.
return "done!";
Here String is your output data type. If its different in your case, you need to change that as well.

Referring to CloudWatch and S3 these services will send out a serialized JSON object as payload. So you can update your lambda handler to accept JSON payload instead of String payload, if you feel its feasible.
