Logic App - get attachment from Email and put it on Azure File Storage incorrect size on Storage

Question

Hello,

I have build Logic App to retrieve attachment from email and put those data to Azure File Storage. I have facing issue that attachment from Email has different size then attachment on Azure File Storage. Additionally attachment created on Azure File Storage are unable to open. I don't retrieve content of the file.

Below flow whitch is retriving data:

Create file has field to get content from Get Attachemnt component:

body('Get_Attachment_(V2)')?['contentBytes']

This action is retrieving email in Get Attachement with content:
Payload retrivet on step:

{
  "@odata.context": "Some value",
  "@odata.type": "#microsoft.graph.fileAttachment",
  "@odata.mediaContentType": "image/jpeg",
  "id": "AAMkADkxMjA2MmQxLTNiNGUtNG",
  "lastModifiedDateTime": "2023-08-10T11:10:25Z",
  "name": "SomeName.jpg",
  "contentType": "image/jpeg",
  "size": 24722,
  "isInline": false,
  "contentId": null,
  "contentLocation": null,
  "contentBytes": "Here is Byte content"
}

And on Create file we get body after creation of file:

{
  "createdDateTime": "2023-08-10T11:11:01.0876467+00:00",
  "lastModifiedDateTime": "2023-08-10T11:11:01+00:00",
  "name": "SomeName.jpg",
  "isFolder": false,
  "path": "asdf/SomeName.jpg",
  "fileSize": 27960,
  "id": "13835110831840296960",
  "etag": "\"0x8DB99927B0A5226\"",
  "contentType": "image/jpeg"
}

As you can see Size is different after creation and I don't know why. And file is unable to open on file share.

I will appreciate if you will be able to help me.

Best Regards,

Hi,

Solution for this to solve is to put in Create file steps that kind of content:

"fileContent": {
       "$content": "@body('Get_Attachment_(V2)')?['contentBytes']",
       "$content-type": "application/octet-stream"
}

Thanks to that our file has been create in correct way.

Thank you Microsoft Support to solve this issue.
