I'm trying to build a flow that uses the Send an HTTP request action to create a draft email, and this video does a great job showing how to do it. However, the example only shows how to hard code a single email address into the JSON. I want to dynamically add an array of email addresses, and I can't figure out how to make it work. I tried initializing a variable, then appending it with a loop based on a conditional field that pulls addresses from a SharePoint list. I then sent the variable to a Compose action, and inserted the Compose output into the JSON. I also tried stripping the brackets, changing the double-quotes (around email address) to single quotes... but nothing worked.
I'm typically getting the error message "were unable to deserialize" or "Unable to read JSON request payload. Please ensure Content-Type header is set and payload is of valid JSON format" - depending on what tweaks I make.
Any ideas?
