Create Message with OneDrive Attachment causes error

[dadams39]

Found a strange error. Using the following API's:

• Send Message
• Add Attachment
  Go.mod

 github.com/microsoftgraph/msgraph-sdk-go v0.40.0
 github.com/microsoftgraph/msgraph-sdk-go-core v0.28.1

Both of the techniques work for an Item Attachment, but for some reason with a OneDrive Attachment, this does not seem to work. Error below:

Is there any additional documentation on how to send a message with a OneDrive attachment?

[dadams39]

This document describes how to add a oneDrive attachment:

The intended message described has an attachment that uses the Upload & Share option.

If you want to attach files from OneDrive/SharePoint (not copying them, but sending a link to them) your application needs to:

1. upload the file to ODSP (if not already there).
2. (optional) create a sharing link if the recipients are outside of the organization.
3. create a draft message
4. create a referenceAttachment (same as add attachment, except with a different class)
5. send the message
