I'm trying to use a Flow to create news links in a modern site when a new post is published to an external site's rss feed.
It appears to get the JSON content correctly but the "send an http request to SP" action fails with this error:
{"odata.error":{"code":"-1, Microsoft.SharePoint.Client.InvalidClientQueryException","message":{"lang":"en-US","value":"Invalid JSON. The property name '' is not valid. The name of a property cannot be empty."}}}
