In Logic Apps, how to add a 'note' to an opportunity in Dynamics Sales

[ksaye]

In Logic Apps, I am able to see accounts, opportunities and such.

I am struggling to add a row (really I want to add a note to an opportunity). I the portal, it is simple, just go to an opportunity look at the time line, click the "+' and add a note:

In Logic Apps, I am attempting to use the 'add a new row' to the table Notes and adding the opportunity id:

It seems the 'regarding opportunity' does not work, as I get the error: "URL was not parsed due to an ODataUnrecognizedPathException. Resource not found for the segment provided in the URL." What am I missing?

                    "connectionName": "commondataservice"
                }
            }
        }
    }
}

I know the opportunityID is correct because the following URL returns the opportunity:

https://orgea675467.crm.dynamics.com/api/data/v9.0/opportunities?fetchXml=<fetch mapping="logical" returntotalrecordcount="true" page="1" count="10" no-lock="false"><entity name="opportunity"><attribute name="statecode"/><attribute name="closeprobability"/><attribute name="customerid"/><attribute name="customerid"/><attribute name="estimatedclosedate"/><attribute name="estimatedvalue"/><attribute name="name"/><attribute name="parentaccountid"/><attribute name="parentcontactid"/><attribute name="opportunityratingcode"/><filter type="and"><condition attribute="opportunityid" operator="eq" value="14741c9e-4b9e-ea11-a811-000d3a1bb122"/></filter><order attribute="name" descending="false"/></entity></fetch>
