I use the old designer and do it this way, which has worked for me:

The name value in the Relative URI value is the filename. With this, first you create the file in Azure DevOps and then attach the file to the item.

Here is the scheme for the Parse JSON action, which is from the body of the prior Azure action:
{ "type": "object", "properties": { "id": { "type": "string" }, "url": { "type": "string" } } }

Hey David MA,

does what you present below create a file then put an attachment in?

What i have takes a microsoft form, then uses a create work item action to add the workitem into devops, THEN i would need a way to add this file to the now existing workitem (these will mainly be screenshots, pdfs and word docs. also some excel sheets eventually.

Thanks!

Yes, what I show creates file in Azure and then adds it as an attachment to your work item. The process I show is from a question in MS Forms that is an attachment. If you are asking if that will work, yes. My process has been in place for at least a year, and I haven't had any issues yet.
