Adding attachment to approval - Creates "Apply to each"

Posted on by HC123

When creating an approval, I wish to attach and attachment which was originally sent via email. Whenever I attempt this, it creates an "apply to each", which I suspect is due to the fact that there could be multiple attachments. There will only ever be one attachment based on the flow I have created. How can I prevent an "Apply to each".

Many thanks

Re: Adding attachment to approval - Creates "Apply to each"

Thank you for your help.

I am running in to issues with the document when attached to an approval. I've tried the below to try and get the content of the file
first(triggerOutputs()?['body/attachments'])
However, the file attaches visually, and the name is shown correctly, but the file won't open or display, regardless of the file type tested.

I've also tried swapping the below 'name' swapped for 'attachment_content', and it returns this error.

Any advise would be greatly appreciated.

Hi @HC123

You could use this expression in a Compose action, for instance. Use the output of the compose action in next steps when you need to access attachment content or attachment name.

Hope it helps now!

Thanks for the detailed information. Could you please clarify where this expression should go? Is it being set in a variable, or elsewhere?

Thanks again.

Hi @HC123

In order to avoid the apply to each, you should get the first attachment within the email using the following expression:

first(triggerOutputs()?['body/attachments'])

assuming you're using the trigger "when a new email arrives".

For instance, if you want to access the attachment name you should write the expression:

first(triggerOutputs()?['body/attachments'])?['name']

And the same for other properties.

Hope that helps!
