Office365.SendEmail with Attachment Error

Hi there, I'm trying to send an email with an attachment that is a csv file of a collection created within the app. I consistently get the same error when I try to use the Concat function to place my collection's data in the attachment's ContentBytes. I've tried the process using Flow and receive the same error. Is anyone familiar with this? Office365.SendEmail failed: One or more errors occurred. Reporting the first one: Bad Request <meta http-equiv="Content-Type" content="text/html; charset=us-ascii" /> Bad Request - Invalid URL HTTP Error 400. The request URL is invalid Thanks, Darian

Hi Mona,


Sorry for the late response. Here is the formula, where SelectedTraining is a collection in the app and CcUser is the current user's email address. 



Office365.SendEmail("", "Subject", "Body", {IsHtml: true,  Importance: Normal, Cc:CcUser, Attachments:Table({Name:"test.csv", ContentBytes:Concat(SelectedTraining, it0l & ", "), '@odata.type':""})})
