Dear Community,

I am trying to send pdf attachment via email and GraphAPI. However, I am unable to get through the contentBytes section. I have also tried sending FileContent directly but unable to.

"contentType": "application/pdf",
  "message": {
    "IsReadReceiptRequested": "true",
    "IsDeliveryReceiptRequested": "true",
    "subject": "@{items('Apply_to_each')?['Subject']}",
    "body": {
      "contentType": "Text",
      "content": "@{items('Apply_to_each')?['NewBody']}"
    },
    "toRecipients": [
      {
        "emailAddress": {"address": "@{items('Apply_to_each')?['EmailTo']}" }
      }
    ],
  "attachments": [
      {
        "@odata.type": "#microsoft.graph.fileAttachment",
        "name": "@{outputs('Get_file_metadata')?['body/Name']}",
        "contentType": "application/pdf",
        "contentBytes": "@{base64(body('Get_file_content'))}"
}
      }
    ]
},
 "save To SentItems": "true",
}

Graph API PDF attachment ContentBytes

This is sending document now. GraphAPI didnt have permissions in AppRegistrations Azure Portal

"contentBytes": "@{base64(body('Get_file_content'))}"
