Good Morning,
I would like to start off by suggesting you block out your orgs information when posting screenshots.
As for your problem I would try a few troubleshooting steps:
Make sure you trigger has 'include attachments' turned on in the dropdown but, since you are referencing it I believe it does.
When you are creating your file make sure the name is carrying the correct extension within it if the files is a .xlsx try to add the extension directly onto the naming convention of the file. You could also use a compose to check before adding it directly.
I personally run into a lot of issues when using the file object directly with the action to send, store or upload it I usually have better luck when I create an array variable before then assign them into the array and swap the actions file mode the array will look something like this:
Inside an apply to each for the attachments
{
"Name": Name,
"ContentBytes": FileContent
}
Hopefully this helps if it solves your issue please select it as the solution if not feel free to follow up and I am sure myself or someone else will continue to assist. Have a good one!
