Problem with Sharepoint list: create item and add attachment

[Teflonreis]

Hello everyone

If an item is created in the secondary list, the primary list shall also be populated with the row including attachments.

The flow works. What does not work yet is copying the attachment from secondary to primary list.

Copying does work if the user field in "create item" is not populated with "user displayname" since apply to each with "user" is built around "create item". Because of "apply to each", the action "add attachment" only displays the wrong id. "add attachment" only worked so far when I use the id "create item".

I am wondering how to populate the field "user" with "user displayname" in "Create item" such that no apply to each is built around it which would result in "add attachment" not displaying the "id" from "create item".

Thanks for any help.

An idea.

Is it possible to write out the suggested dynamic content that IS NOT displayed in ADD ATTACHMENT?

"id" inside "create item" inside "apply_to_each". Something like this ? items('apply_to_each')?['id']
