Posted on by KS-27121428-0

I've been working on this flow for days with no success so I'm turning to the Power Community.

My goal is when I receive a new email with attachment (export from ServiceNow), I want it to save the CSV file to my sharepoint site.

The flow keeps failing at the Apply to each loop.

For one thing, you've got nested "Apply to each" loops (the "Apply to each" inside the "For each 1"). This is almost never what you want to do.

The new flow designer tends to do this automatically unfortunately, which I consider basically a bug. So you have to be careful, I've seen it create a new loop every time I drop a dynamic reference from the same array into an action.

Try moving the "Apply to each" out of the "For Each 1" loop and make sure its input is the attachments array.

If you still have trouble, post some screenshots showing your inputs for the apply to each loops, as well the references you've put into the "Get Attachment" action.

Also post the complete error message if it continues.

Yes it's so annoying that it creates this loop and I'm still very new to this. Should I start using the old designer with future flows?

I removed the loop but the error I'm getting now is "The input parameter(s) of action 'Get_Attachment_(V2)_2' contain an invalid reference to 'Get_Attachments_(V2)'. Correct to include a valid reference to 'Get_Attachments_(V2)' for the input parameter(s) of action 'Get_Attachment_(V2)_2'."

Using AI, it suggested instead of using attachment ID (since it creates the loop) that I use this formula for Get Attachment (V2) 2:

first(body('Get_Attachments_(V2)')['value'])['Id']
