I am uploading files from front end (Angular) using multipart/form-data to S3 via AWS Lambda. I have installed the serverless-apigw-binary 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
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.
Am I missing any step? What is the correct way to accept binary files in Lambda?
