Bad Request 400 when Uploading file to an object

Question

I am getting below message when adding file to an existing object. I m using c#: 
 {"Status":400,"URL":"/objects/0/18222/latest/files/upload","Method":"POST","Exception":{"Name":"ArgumentException","Message":"Malformed data."},"Stack":"Error reference ID: ccff6cb1-a969-4574-beac-fe7bbeb2e7a6","Message":"Malformed data.","IsLoggedToVault":true,"IsLoggedToApplication":true,"ExceptionName":"ArgumentException"} 
 Below is my request: 
 
 {"UploadID":4,"Title":"test1234","Extension":"txt","Size":40,"FileInformationType":0,"TempFilePath":""} 
 
 Thanks

That doesn't look right. 
 The URI should be "/objects/{objectTypeID}/{internalObjectID}/{version}/files/upload". "version" can be the string "latest" in some situations too. 
 Also be careful that the display ID may not be what you want. Read more here: Internal and External IDs (m-files.com) 
 You probably want: 
 // Without a specific version number (always the latest one available to this user):
var uri = "https://.../REST/objects/" + results1.Items[0].ObjVer.Type + "/" + results1.Items[0].ObjVer.ID + "/latest/files/upload";

// With a specific verison number:
var uri = "https://.../REST/objects/" + results1.Items[0].ObjVer.Type + "/" + results1.Items[0].ObjVer.ID + "/" + results1.Items[0].ObjVer.Version + "/files/upload";

Something about this forum software interferes with links. It seems to truncate them (adding in "..." and shortening them) quite a lot. It makes it difficult to see exactly what you're doing. 
 The point I was making was to double-check the IDs, and to not use the DisplayID in the path (DisplayID may or may not be the same as the internal ID, and that could be what's going wrong here depending upon the vault itself).

I think the data you send should be a collection. So something like this: 
 [{"UploadID":4,"Title":"test1234","Extension":"txt","Size":40,"FileInformationType":0,"TempFilePath":""}]
