Hi,
When I test the flow using the the Automatic method the result is different than the manual test. I have a simple Flow which is basically get email and forward it with an attachment. The attachment is coming from the original email.

When I manually trigger a test the attachment is sent as is but when I trigger the test using the automatic method the attached just contains the content type as text as show below.

I am not sure why this occurs but I wasted the whole day to test the flow thinking I was doing something wrong to find out that only in the automated tests this issue was occurring.
