I'm trying to send one image to my Lambda Function using Python just to test for one project, but Postman is giving me one error and I don't know how to solve it.

My code is simply to detect if I have some data in the key **"image"** and return some message. I'm using Postman to send the POST request, I clicked in the **Body** tab, selected the form-data option and I wrote **image** for the key and selected the image file from my computer (the image size is 27 kb). This is the code in my Lambda Function:

```
def lambda_handler(event, context):
    if event['image']:
        return {
            "Message": 'Everything went ok'
        }

```

And this is the error message that I'm receiving from Postman:
