Find Files in Folder by Path - Returns Empty Body

[VGoncalves]

Hello,

I have a flow that sends an approval email with the link of a file to a supervisor.

It works sometimes perfectly, but sometimes dont.

Sometimes the link isnt on the email, i had a few complains and when i saw the flow, i notice that sometimes the Find files in Folder by path the body is empty (like you can see on the image below)

I went to check with a few users that send the approval email and the users, that gave this error, have the file on the folder. 

And i can't see any pattern for this to be happening...

As anyone have any idea why is this happening?

The flow goes like this:

First i initialize a variable, then find the files, then with the apply to each create a share link with the folder founded and then set the variable with said link

And is the variable i put on the email
