I have successfully sent an Attachment using Power Automate, the problem is the Attachments that are sent cannot be viewed and even if it is downloaded it doesn't show anything.
These are the Blocks that I've used.

This is the Block where I am attaching the Attachment to the Email.

This is the Email with the Attachment.

but once you click the Attachment it wont open.

even if it is downloaded.

Been stuck for an hour now thinking possible error though there's no Error on Power Automate.
