Get Attachment V2 - Bad Request

Posted on by MarekFe

Hello,

I'm creating a flow where I need to get content of a csv attachment from shared mailbox.

Flow triggers correctly & condition identifies correct attachment.

Then the Get Attachment V2 fails with a Bad Request error message.

I see that the input is correct.

I dont uderstand why the output gives me this message:

{"statusCode":400,"headers":{"Date":"Thu, 11 Jan 2024 12:57:29 GMT","Connection":"close","Content-Type":"text/html; charset=us-ascii","Content-Length":"324"},"body":"<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01//EN\"\"http://www.w3.org/TR/html4/strict.dtd\">\r\n<HTML><HEAD><TITLE>Bad Request</TITLE>\r\n<META HTTP-EQUIV=\"Content-Type\" Content=\"text/html; charset=us-ascii\"></HEAD>\r\n<BODY><h2>Bad Request - Invalid URL</h2>\r\n<hr><p>HTTP Error 400. The request URL is invalid.</p>\r\n</BODY></HTML>\r\n"}

All I'm looking for is to get the "contentBytes"of the attachment for further processing.

Please help.

Thank you

Kind Regards

Marek

Re: Get Attachment V2 - Bad Request

Now that I posted this message I see that instead of using Attachment ID I added the whole attachment in the ID field.

How do I get just the Attachment ID from the output of the condition ?

{ "@odata.type": "#microsoft.graph.fileAttachment", "id": "AAMkADFiZjZhNgAQAO99MC-1PfJHn_4AnkXCJ4c=", "lastModifiedDateTime": "2024-01-11T12:57:11+00:00", "name": "Daily PDC_2024-01-10.csv", "contentType": "image/jpeg", "size": 1312, "isInline": false, "contentId": "2B29D731546@eurprd01.prod.outlook.com", "contentBytes": "U3RhdGlzdGljcyB" }

Thank you

Soo I found the solution.
I just run the condition output through Compose.
Then reference contentBytes from the Compose Array.

Still I would like to know if there is a way to use the Get Attachment V2 ?

Thank you
Kind Regards
