title: How to upload multipart form data in serverless
body: <p>I am uploading files from front end (Angular) using multipart/form-data to S3 via AWS Lambda. I have installed the <a href="https://github.com/maciejtreder/serverless-apigw-binary" rel="nofollow noreferrer">serverless-apigw-binary</a> plugin and in my serverless.yml have included the configuration as mentioned in this plugin's documentation. On my API gateway I can see that the plugin adds the binary media types values mentioned in the serverless.yml file</p>
  
  <p>However when I view the file on S3 it is corrupted. Does not matter what type of file I upload (image, doc, pdf) I cannot open it on download. This issue is also present when I make a direct POST request to my lambda function from Postman.</p>
  
  <p>Am I missing any step? What is the correct way to accept binary files in Lambda?</p>
