Mime attachment in vRA

Hi all,

I have created a workflow that uses mime attachment as an input parameter, to upload a .csv file. The flow works flawlessly and does what it is suppose to do.

Now I want to use the flow as a Service and I have uploaded it into vRA as a Advanced service. The problem i get is when run in vRA the mime attachment input gives me no option to upload the file. Is there a alternative to mime attachment?

The Flow in vRA should allow the user to upload a .csv file from him local machine and the flow should be able to read the file to process it further.

Thanks in advance.
