Hello all, I'm trying to take a form submission and pump it into Planner, I want users to be able to upload documents to sharepoint using the form and that all works great, the part that doesn't seem to be working so great is taking it from sharepoint and attaching it to the planner task. I keep getting the "Property references in payload has a value that does not match schema." error. Even when I let the connection create the json for me rather than collecting all the attachments in an array and adding them all at once.
I'm at wit's end with this one folks, I've been working on it off and on for weeks. See screen caps of the relevent bits below:


Here you can see the input that it's trying to use:

Any and all help is appreciated at this point. Thanks everyone
