Write File to netapp using rest api

[Philippschumacher]

I am currently migrating our old code accessing netapp using ontap and replacing it by using REST. 

I tried to write a file to netapp using POSTMAN by calling the following URL (http method POST):

https://ms-netapp.m-s.ch/api/storage/volumes/{volumeid}/files/{path}

My content type is multipart-formdata and I have two elements in it

first element: Json with the following content.

{

"target": "Test",

"is_empty": "",

"name": "Test.pdf",

"path": "TestPH",

"type": "file"

}

second element: my actual file

this leads to an http-400 error without further information about the cause. The funny thing about it is, that if I remove the second element, it creates a file that contains the submitted json. 

I tried to implement the api using the following information: https://docs.netapp.com/us-en/ontap-restapi-9121/ontap/swagger-ui/index.html#/storage/file_info_create
