Unsupported Media Type with Spring Boot and Serverless

Question

I am building application with Spring Boot (Serverless project) to deploy in AWS Lambda. I have a method that consumes application/x-www-form-urlencoded . When I call method in localhost 415 appear:

Content type 'application/x-www-form-urlencoded;charset=UTF-8' not supported

I attach method code and yaml configuration, I think that problem is Serverless configuration, because this method works in other project (NON-Serverless).

Method :

 @PostMapping(name = "/createpayment", consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE)
    public String createPayment(@RequestBody Payload payload) throws StripeException, IOException, MessagingException { 
         ...
 }

Yaml :

AWSTemplateFormatVersion: '2010-09-09'
Transform: AWS::Serverless-2016-10-31
Description: AWS Serverless Sansaru Payments - com.sansarushop.payments::sansaru-payments

            Method: any
      Environment:
        Variables:
          SPRING_PROFILES_ACTIVE: 'prod'

Outputs:
  SansaruPaymentsApi:
    Description: URL for application
    Value: !Sub 'https://${ServerlessRestApi}.execute-api.${AWS::Region}.amazonaws.com/Prod/ping'
    Export:
      Name: ExamplePaymentsApi

Thanks for your help!

The problem is with mediatype application/x-www-form-urlencoded, Spring Boot doesn't understand this with RequestBody. So, if you want to use, please remove the @RequestBody annotation from method.

@PostMapping(name = "/createpayment", consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE)
public String createPayment(@RequestParam Map<String, String> params) throws StripeException, IOException, MessagingException { 
         ...
 }
