Getting a "NoSuchKey" when using signed URL but theobject exists.

[YasenMakioui]

I've been using the solution and it meets our needs but anyone can make calls to the Image Handler (Public endpoint).

I've checked the security section in the documentation and enabled CloudFront signed URLs. The problem comes when I make a request adding the correct signature. I get a "NoSuchKey" error but when I checked the bucket the object is right there.

{"status":404,"code":"NoSuchKey","message":"The image rabbit.jpg does not exist or the request may not be base64 encoded properly."}

Since the object exists my guess is that it has something to do with the encoding but I didn't find nothing related in the documentation.

Am I missing out something? What I'm doing is using the path and the hmac library in python to generate the signature and then adding that signature with the signature querystring:

https://<endpoint>/0x1024/filters:format(jpeg)/rabbit.jpg?signature=<signature>

@YasenMakioui We will investigate and get back to you

@YasenMakioui We just tested this without any trouble. The requested image was found and returned.

The python that we used was:

import hashlib
import hmac

my_secret = 'mytestsecret'
path = '/0x1024/filters:format(jpeg)/image.jpg'
secret_encode = my_secret.encode('utf-8')
path_encode = path.encode('utf-8')
signature = hmac.new(secret_encode, path_encode, digestmod=hashlib.sha256).hexdigest()
print(signature)

The request would be similar to this:

https://xxx.cloudfront.net/0x1024/filters:format(jpeg)/image.jpg?signature=<output from python>

It looks like I tried to acces an existing URL. In th documentation (page 12 of the pdf) is specified that:

NOTE: If you update your existing solution deployment and activate the image URL signature,
the updated stack will no longer be compatible with the existing URLs. You must update
your application to provide the correct signature query string to your URLs. To update the
solution stack, refer to Update the solution.

I tried with another image and it works fine with the code you provided.

Thank you very much!
