Hi all,

I tried to create a flow to 'copy' an image, which is stored as an attachment of a list entry in SharePoint to OneDrive.

To accomplish this I tried the following action steps:

The run fails with the following error:

The error message was:

"status": 400,
"message": "Route did not match\r\nclientRequestId: 5b72a24d-070d-4cde-b714-7ccc02591540\r\nserviceRequestId: 5b72a24d-070d-4cde-b714-7ccc02591540"

Unfortunately I do not have any ideas how to analyse the problem. As you can see, I use fixed ID ('1') and tried to get the file identifier as a result from 'get attachments' action. Which were successful and delivers 2 files as a result as expected...

Hope I missed something, since I have no more ideas.

Thanks a lot!

Please try the following expression to get the File Identifier:
items('Apply_to_each')?['Id']
Example of the content of Body from one of my flows:

Thanks @ekarim2020!
That was the missing part...
BTW: I would like to find those identifier (ie Id) directly inside the dropdown 😉
Thanks again!
Cheers

In this example, as it's simple flow, it's a easier to demonstrate:

I am a bit confused, as the ID of 'Get attachments' is not expected to be existing, since 'Get attachments' contains the information of ALL attachments, whereas the 'body' of 'Apply to each' contains only the one of the current loop...
But Thanks!

The Get Attachments action returns the Id of the attachment (the File Identifier) - not be be confused with the SharePoint List item ID:

Hope this helps.
