Description

Unable to add an expiration to MyDrive folders to share permissions associated with the folder if the destination user's Role is writer or commenter. If the role is reader, the expiration addition succeeds.

This makes it difficult to manage external sharing permissions for collaborative folders.

Code

	newPermission := drive.Permission{
		Role: "writer",
		ExpirationTime: desiredExpirationTime.Format(time.RFC3339),
	}

        // Note, the high level funct is calling: perm, err := d.svc.Permissions.Update(fileId, permissionId, permission).Fields("*").UseDomainAdminAccess(false).SupportsAllDrives(true).Do()
	_, err := UpdateFilePermissionHighLevel(NewDriveService(ctx, option.WithHTTPClient(config.Client(ctx))), driveFileId, oldPermission.Id, &newPermission)
	if err != nil {
		log.Fatal(err)
	}

Output

googleapi: Error 403: Expiration dates cannot be set on this item., cannotSetExpiration

Steps

1. Create MyDrive folder
2. Add an Editor (writer) or Commenter (commenter) sharing permission for another user via the UI
3. Attempt to add an expiration date via the API, preserving the previously defined Role
