A flow has been prepared in such a way that all the attached files through the outlook mails are saved in a specific folder of SharePoint site and it is working fine. But the size of all the saved file is becoming 4 bytes. as a result none of the files are opening.

Any email arrives.

Attachment is copied to a specific SharePoint folder.

All the files are saved with a fixed size of 4 bytes.
Please guide me with a solution.
