This is the notification I receive when a new item is submitted by SP users other than me. I can post a new item and notifications are sent correctly. For others, this alert flow does not trigger. The "Comment" field is set to optional.
Error detailes: The API 'sharepointonline' returned an invalid response for workflow operation 'When_an_item_is_created' of type 'OpenApiConnection'. Error details: 'The API operation 'GetOnNewItems' is missing required property 'body/value/0/Comment'.'
Any idea?
