I am working on a simple flow to send an email when a record is created in dataverse.
One of the columns is an image column, that is added as an attachment to the email.
It works well when there is an image (it is optional), but there is an error when there is no image.
Here is how I get the image.

How to check if an image exists? or to avoid the "attachment can not be blank" error?
Thanks!
