upload jpeg to lambda

Question

Help!

I am uploading an image to lambda and in the body it appears like so (and isBase64 is **false**):

```

Content-Disposition: form-data; name="files"; filename="playing.jpg"
Content-Type: image/jpeg


 $.' ",#(7),01444'9=82<.342��C			
```

Now, the documentation is really not too clear to me when it says:

"To handle binary payloads for AWS Lambda proxy integrations, you must base64-encode your function's response. " (https://docs.aws.amazon.com/apigateway/latest/developerguide/api-gateway-payload-encodings.html). I've tried converting the image below to  base64 to no avail. I am not even sure what is this encoding...???

This is what i tried (nodejs 14):

```
Buffer.from(file.buffer, 'binary').toString('base64'),
```

The image won't turn up though. Any thoughts?

the first 3 bytes are

```
00000000: 11101111 10111111 10111101 11101111 10111111 10111101

```

or  `0xef 0xbf 0xbd`...

Any thoughts?

Answer

I had a similar problem, you may need to set BinaryMediaTypes
If you are using SAM, add the following settings to your template file :

```
Globals:
  Api:
    BinaryMediaTypes:
      - image/png
      - image/jpg
      - image/jpeg
``

Or try adding the same in  API Gateway > Settings > Binary Media Types
