Do you get an error when trying to upload image files using the API?
S3 File Upload URL error:
<Message>The request signature we calculated does not match the signature you provided. Check your key and signing method.>
Here are some troubleshooting steps, along with a video for your convenience!
1. Make sure the `filename` parameter in your POST to `documents/modify` and `documents/add` matches the filename that you upload. e.g. If I am uploading an image titled "tree.jpg", then I'll need to set the `filename` parameter of the `documents/add` method to "tree.jpg" exactly.
2. The URL expires after a short time, so you must PUT the file to thes3.amazonaws.com URL right after you get a result from the `documents/add` method. While testing, I usually call the PUT method to amazon within 30 seconds after the POST method to L2L.
3. Make sure you are including all required fields in the `documents/add` method.
