Hi mjbaylon,

The error is occurring because you are sending a list of text values instead of a list of custom objects in your email. Please correct this to resolve the issue.

As @Deenuji Loganathan pointed out you need to have List of custom objects for the attachments.

I would not use list but just set variable.

Here is how you can make it work:

Send an email (V2) Attachemnts field put the %Attachments% variable

Here is code for the actions (other than the Send an email V2 since it has connection reference that would not work on your flow).
Folder.GetFiles Folder: $'''C:\\Users\\YourUserName\\Documents\\Test''' FileFilter: $'''*''' IncludeSubfolders: False FailOnAccessDenied: True SortBy1: Folder.SortBy.NoSort SortDescending1: False SortBy2: Folder.SortBy.NoSort SortDescending2: False SortBy3: Folder.SortBy.NoSort SortDescending3: False Files=> Files SET FirstFile TO True LOOP FOREACH CurrentItem2 IN Files File.ConvertToBinary File: CurrentItem2 BinaryData=> BinaryData IF BinaryData = $'''Byte [0]''' THEN # No file. Might be folder so go to next loop. NEXT LOOP END File.GetPathPart File: CurrentItem2.FullName RootPath=> RootPath Directory=> Directory FileName=> FileName FileNameWithoutExtension=> FileNameNoExtension Extension=> FileExtension IF FirstFile = True THEN SET FirstFile TO False SET Attachments TO [{ 'Name': CurrentItem2.Name, 'ContentBytes': BinaryData }] ELSE SET Attachments TO Attachments + { 'Name': CurrentItem2.Name, 'ContentBytes': BinaryData } END END
