Attachments become corrupted when emailed via an attachment array

Hello,

I'm trying to include attachments from an attachment field in a SharePoint list so that multiple attachments may be dynamically included. I'm able to set up the array and send attachments, but they become corrupt and can't be opened.

What might I be doing wrong in my flow?

The current structure is:

- When a new item is created

- Initialize array variable

- If has attachments is true

- Get attachments, ID from the list item created

- Apply to each, body from Get Attachments

- Get attachment content, ID = ID from list item, File identifier = Id from Get Attachments

- Append to array:

{
"Name": "@{items('Apply_to_each')?['DisplayName']}",
"ContentBytes": "@{outputs('Get_attachment_content')?['body']?['$content']}"
}

- Send an email, attachment array in the attachments field

What is the file type of your attachments? Try adding the file type to the file name using concat().

For example, if your file types are PDF:

{
"Name": concat("@{items('Apply_to_each')?['DisplayName']}", '.pdf'),
"ContentBytes": "@{outputs('Get_attachment_content')?['body']?['$content']}"
}

Hi @SA-25051734-0

The first thing to do is to try removing the quotes around the ContentBytes section of your array:

{ "Name": "@{items('Apply_to_each')?['DisplayName']}", "ContentBytes": @{outputs('Get_attachment_content')?['body']?['$content']} }

If this error is still happening after that, sometimes (but not always) there is a known issue on the official documentation page (scroll down to the screenshots to see this part), you'll need to use the new attachments array format:

{ "Name": @{items('Apply_to_each')?['DisplayName']}, "ContentBytes": { "$content": @{outputs('Get_attachment_content')?['body']?['$content']}, "$content-type": @{outputs('Get_attachment_content')?['body']?['$content-type']} } }

Between these two options, one of them should resolve the issue.

Thank you @Tomac, the new attachments array format worked! The image emailed successfully and was not corrupted. I have not tested this with multiple files in the array, but feeling good about it after overcoming this hurdle.
