Dropbox v2 upload cursor offset confusion

That error indicates that you're supplying an incorrect offset value for this upload session when uploading a chunk of data. The error includes the correct value, but you'll need to debug your code to see why you're not sending it in the first place. (I don't see where you update the offset value in your code, for example.)
There's a basic example of using upload sessions with the Python SDK here:
A 'path/conflict/file' error indicates that the upload failed because there is already a file at the specified path.
You should instead specify a different path, or supply a different WriteMode to to files_upload_session_finish in the CommitInfo to automatically handle the conflict.
I have the variable `a` for offset.
Now i'm getting UploadSessionError('path',WriteError('conflict',WriteConflictError('file',None))))
Now i'm getting UploadSessionError('path',WriteError('conflict',WriteConflictError('file',None))))

- thanks Now the problem is the offset of files_upload_session_finish , I am using the content length for the offset but it is giving error
Code:
import dropbox,requests,sys
def down(url):
dbx=dropbox.Dropbox(AccessToken)
size=45*1024
a=0
i=0
p=0
params = {'':'', 'render':'download'}
r=requests.get(url,params=params,stream=True)
clen=r.headers['Content-length']
for chunk in r.iter_content(chunk_size=size):
if chunk:
i+=1
a+=len(chunk)
c=a/(1024)
print('\n'+str(c)+' of '+str(clen))
if i==1:
strtid = dbx.files_upload_session_start(chunk)
cursor = dropbox.files.UploadSessionCursor(session_id=strtid.session_id,offset=len(chunk))
commit = dropbox.files.CommitInfo(path='/sourttt',mode=dropbox.files.WriteMode('add'))
if ((int(clen)-p))<=size:
cur=dropbox.files.UploadSessionCursor(session_id=strtid.session_id,offset=int(a))
dbx.files_upload_session_finish(chunk,cur,commit)
else:
dbx.files_upload_session_append(chunk,cursor.session_id,a)
p=a
url='https://speedtest.ftp.otenet.gr/files/test100k.db'
down(url)
Error:
dropbox.exceptions.ApiError: ('281cb346aa41adc8436f415fc4d0de0a', UploadSessionFinishError('lookup_failed', UploadSessionLookupError('incorrect_offset', UploadSessionOffsetError(correct_offset=138240))))
The content length is 100Kb(102400) but the error showing me the correct offset is 138240 and the difference between those are 35Kb . What should I do for offset value in files_upload_session_finish
?- Greg-DBThe offset value works the same way for files_upload_session_finish as it does for the other calls. It should match how much data you've uploaded in the upload session so far.
It sounds like you may have a bug where you're uploading more data than expected. I recommend adding extra logging or working through your code in a debugger to determine where the discrepancy is taking place.- At the first initialisation for cursor the offset value is 45kb. And I am trying to upload 100kb file .so after 2 iterations uploaded data is 90kb and on finishing I have set the cursor.offset to total size of the file that is 100kb ,but it is returning error saying the correct offset is 135kb .45+45+45=135kb , on third iteration which is last it is showing that it needs the correct offset is 135kb but the original file length is only 100kb. So what am I missing?
In python with sessions upload add the parm mode=dropbox.files.WriteMode('overwrite')
To overwrite the file with the name already exists
