SES V2 Sending Wrong Attachment File

[berviantoleo]

I'm curious how the Memory Stream changed into an encoded base64 string. I try to check the length of the Memory Stream and it seems it has the expected size. However, when receiving the email. I got the bigger size attachment file and the attachment file was wrong. I got the correct amount of pages (this is a PDF file). However, all the pages are blank.

I'm looking for another root cause that may be possible. The issue may come when I provide the wrong MemoryStream (maybe).
