Support on cache by body on POST request

[leeboy1984]

Hi,

I'm getting "Internal Server Error" when I'm trying to configure a POST request.

Here is my function definition

postCached:
    handler: src/handlers/postCached.handler
    events:
      - http:
          path: /cached/test
          method: post
          cors: true
          caching:
            enabled: true
            cacheKeyParameters:
              - name: integration.request.header.bodyValue
                mappedFrom: method.request.body

And a body example:

{
  "email": "foo@bar.xyz"
}

What is wrong?

Hi @leeboy1984,

Could you please check if your endpoint works when the caching plugin is not used? For example, you could remove it from the serverless.yml plugins section.

Thanks.

[leeboy1984]

Yes! It works perfectly if I remove the cache config or remove the plugin

Hi @leeboy1984,

Could you please try adding integration: lambda to your event?

For example:

events:
  - http:
      path: /cached/test
      method: post
      integration: lambda

[leeboy1984]

No, if I add that type of integration somehow lambda is not getting executed, fails before even calling the handler

[leeboy1984]

The error I'm getting from API Gateway is the following:
Execution failed due to configuration error: Unable to transform request

Any suggestion/idea?

[leeboy1984]

I have found the problem, problem is related with binaryMediaTypes, if for any reason you have binaryMediaTypes: / lambda integration does not work
