Attaching File to SharePoint List Item

I am trying to attach files to a SharePoint list item but I keep getting an error message that says file name is required.

My code is below. I have used this approach before without error but this time it's not working.

The workflow works when running it manually and attaching a file right at the workflow.

ForAll(attNewRequestAttachments.Attachments As _attachment,
    ITRequestAddTicketAttachments.Run(
        Value(7),
        {
            contentBytes: _attachment.Value,
            name: _attachment.Name
        }
    )
);

Here is my Power Automate configuration

Here is the error in the workflow

Hello @FW-07051511-0,

This error "Value must be provided in file name" usually means that the SharePoint Add attachment action is not receiving a file from Powerapps, it's empty due to this you are getting the error:

Issue is that the flow expects a file object, but the file properties are being passed directly due to this file is passing empty in automate.

Try passing the file parameter like this:

ForAll(attNewRequestAttachments.Attachments As _attachment, ITRequestAddTicketAttachments.Run( Value(7), { file:{ contentBytes: _attachment.Value, name: _attachment.Name } } ) );

Your trigger is configured to ask for the ID of the item and the filename. But your ForAll is passing the file name and the content bytes. You are passing the wrong parameters.
