What is wrong with attachment content?

[Lars21]

Hi all, 

I have a simple flow which saves invoice pdf's from incoming e-mails to a sharepoint libary.

To create the file I use the "creat file" action as flows:

Last friday I wanted to implemtent this for a customer,  but the Create file action created unreadable files. Today I rebulid the action in another flow and the result was the same, the pdf file is unreadable. 

So I build a "get attachment" step in flow and used it's "content bytes" instead. This works.

So my question is, why does "attachments content" works in one of my flows and others not with the same fileformat? 

PS:
the content bytes solution creates a pdf file with a "real" size, the attachments content solution creates a file with a size of "4".

HI @Lars21 ,

This is a bug.

The exception that you get is because the file is generated incorrectly. Your logic is 100% correct, but the file is saved only with 4bytes.

Please use this method to get PDF files correctly
