Getting an error when requesting new uploaded images

[YasenMakioui]

I've implemented the signed URL following the guide. Making a request to an image that was already in the bucket worked fine, but for new images I get the error:

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

I'm signing the URLs using python:

import hashlib
import hmac

my_secret="mysecret"
path="/1000x1000/filters:format(jpeg)/dog.png"
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)

When making a request to an already uploeaded image "cat.png" the request works fine, but after uploading the "dog.png" image, I get the error.

The image is uploaded, so the "NoSuchKey" does not make sense. For the base64 message, I checked the log stream and found the log message "INFO Path is not base64 encoded.".

In summary, my question is, do I have to do something when uploading new images? Am I doing something wrong here?

Again, thanks for the support since my last two questions were answered.

The INFO message "Path is not base64 encoded" doesn't seem to indicate any problem since it appears on the succesfull requests as well.

After debugging the application, I found that the solution was pointing to a different bucket.
