Manipulating PowerPoint Presentation issue with Aspose.Slides Cloud cURL

When using the Aspose.Slides for Cloud REST API (v1.1) and calling the Slides resource, I receive a status 400 error response with the message “Parameter is not valid.” on certain files.

I’ve attached an example file that causes the error. I’m confident the problem is file-specific and not the API request itself. It appears the underlying issue may have something to do with embedded images.

Incidentally, the Aspose API should return a status 5xx code (indicating a server error) rather than a status 4xx code (indicating a client error) in situations like this.

Please help.



Hi Geoff,

Thank you for your interest in Aspose.Slides.

I have observed your comments and like to request you to please share with us the code sample which you are using on your end so that I may investigate it further to help you out.

Best Regards,

curl https://api.aspose.cloud/v1.1/slides/.../slides?folder=...&storage=s3&appSID=...&signature=...

‘…’ represents actual data that I have removed due to security. Does that help?

I understand that you want to rule out user error, but I can assure you that this call works with other files stored in the same s3 bucket using the same logic for signature generation, etc.
