Can not upload large file by chunks
I am trying to upload file by chunks. Here is my code
self.client.files.uploadSessionStart(input: chunkOfData).response { response, error in
if let result = response {
// the call succeeded
print(result)
while(end < fileSize) {
end += self.CHUNK_SIZE;
var chunkOfData = data.subdataWithRange(NSRange(location: end, length: self.CHUNK_SIZE)) // get range of bytes from file
self.client.files.uploadSessionAppendV2(cursor: Files.UploadSessionCursor(sessionId: result.sessionId, offset: end), input: chunkOfData)
}
// we're ready to finish the upload and commit the file
self.client.files.uploadSessionFinish(cursor: Files.UploadSessionCursor(sessionId: result.sessionId, offset: end),
commit: Files.CommitInfo(path: self.filePath),
// no additional data to add at this point in this case
body:NSData()).response { response, error in
if let result = response {
print(result)
}
else {
print(error!)
}
}
} else {
// the call failed
print(error!)
}
}
Please help what am I doing wrong.

What specifically isn't working as expected? Are you getting an error?
There's a sample here that may be helpful:
Hi Gregory,
I too am unable to upload a file in chunks. As far as I remember this used to work earlier for sure. I am using v2 API. The error occurs at the /finish stage. The exact error is:
Error transferring https://content.dropboxapi.com/2/files/upload_session/finish - server replied: Bad Request
With HTTP status Code: 400
The /start and /append_v2 sessions works and return Status Code: 200.
P.S: I'm using REST API v2.
Steve M.uosuser, please create a new thread to get help with your issue, and please share the body of the 400 response. (The body should be JSON that describes the error.)
