Lambda receives a JSON event object, as such, you must encode binary data before including it in the JSON and passing it to Lambda.
how can this be done because I am struggling with it. I have this script for API call:
<script> document.getElementById('upload-form').addEventListener('submit', function(event) { event.preventDefault(); var formData = new FormData(); formData.append('image-file', document.getElementById('image-file').files[0]); formData.append('watermark-text', document.getElementById('watermark-text').value); formData.append('watermark-color', document.getElementById('watermark-color').value); formData.append('watermark-size', document.getElementById('watermark-size').value); var xhr = new XMLHttpRequest(); xhr.open('POST', 'https://564zhl19u2.execute-api.us-east-1.amazonaws.com/watermark'); xhr.onload = function() { if (xhr.status === 200) { var response = JSON.parse(xhr.responseText); document.getElementById('result').innerHTML = response.message; if (response.image_url) { var downloadLink = document.createElement('a'); downloadLink.href = response.image_url; downloadLink.innerHTML = 'Download Watermarked Image'; downloadLink.setAttribute('download', ''); document.getElementById('result').appendChild(downloadLink); } } }; xhr.send(formData);
