Add attachment to Jira ticket with Azure Logic Apps

Question

I working on a website that allows users to fill and upload files to a form. This form will be sent to Jira, creating a new ticket. I am doing this integration using Logic Apps, if the user doesn't attach any files, the Logic App works fine, but every time someone adds a file, the file is not added to the ticket but also creates a loop sending loads of emails to the user. Does anyone know how could be done? And if I need to add a function to Azure Function, could someone point me out in the right direction? :)

In the payload, the number 13 is the uploaded files
