Hi Gurus,

I’m configuring a REST API which have format as multipart/form-data.  
I created parameter where type put as above.

When tested with operation designer , it shows me below error.

br /\>  
**Warning** : Missing boundary in multipart/form-data POST data in **Unknown** on line **0**  
  
So where to put boundary because when I call it in postman it shows  
multipart/form-data; boundary=

Any help is appreciated.

BR,  
Bhaskar
