Hello guys,

We are developing a mobile app on VBCS and we want to add an attachment to the Purchase Documente, just like it's done on Oracle ERP Cloud. In order to do that, we found the 'Add a task attachment' REST API and we tried to call it on Postman, but we are receiving error 500 as a response.

On Postman, we are passing the content-type as multipart/mixed and adding the attachment on body -> form-data -> change 'Key' to file and select the file on 'Value'.
