Trying to take attachment from Forms and inserting into Approvals

(0) Share

Report

Posted on by Community Power Pla... Microsoft Employee

I have a form that takes an attachment as one of the questions. It is always just 1 excel file (xlsx). Then I need to take the attachment and insert it into an Approval. No changes need to be made to the file in the process. I've tried several things, but I always end up with a message from Excel saying that the file is corrupted. If I specify the MimeType (which I've verified several times is the correct MimeType), then the Approval message doesn't include the attachment.

When trying that solution, I receive an error stating that the file cannot be found.

Hi @Anonymous,

In the Apply to each 7 loop, make sure that the you have used the json function. The expression “wraps” the dynamic content for the Upload your file question inside a json function as shown in the tutorial:

And the Get fie metadata should use the following expression (we aren't using the Parse JSON action so we can select the properties we need):

items('Apply_to_each_7')?['id']

I've used both the above and the JSON block as seen in my screenshots. Both options lead to the same error.

Hi @Anonymous ,

Your flow should be similar to the following:

Note the expression in the Apply to each loop. Please try this in place of the values from Parse JSON:

ouput from previous steps:
json(outputs('Get_response_details')?['body/r5e6b44f5381945f8b67044280e9ef4a4'])

Get file metadata:
items('Apply_to_each')?['id']
