Upload Error with v2 (migration from v1)

    Ok after some investigating I have noticed the first attempt gives no errors, all subsequent attempts give the client modified nonetype error.

     

    After some googling I finally came accross some info that this is a known issue with datetime in python.

     

    I found this:

    try:
    datetime.strptime(date_string, format)
except TypeError:
    datetime(*(time.strptime(date_string, format)[0:6]))

    So I decided to manually tweak the make stone friendly function in the api to this.

    def _make_stone_friendly(
        data_type, val, alias_validators, strict, validate, for_msgpack):
    """
    Convert a Python object to a type that will pass validation by its
    validator.

    Validation by ``alias_validators`` is performed even if ``validate`` is
    false.
    """
    if isinstance(data_type, bv.Timestamp):
        try:
            ret = datetime.datetime.strptime(val, data_type.format)
        except:
            print("datetime.datetime.strptime(val, data_type.format) returned NoneType. Trying alterntive")
            pass
        try:
            ret = datetime.datetime(*(time.strptime(val, data_type.format)[0:6]))
        except (TypeError, ValueError) as e:
            raise bv.ValidationError(e.args[0])
    elif isinstance(data_type, bv.Bytes):
        if for_msgpack:
            if isinstance(val, six.text_type):
                ret = val.encode('utf-8')
            else:
                ret = val
        else:
            try:
                ret = base64.b64decode(val)
            except TypeError:
                raise bv.ValidationError('invalid base64-encoded bytes')
    elif isinstance(data_type, bv.Void):
        if strict and val is not None:
            raise bv.ValidationError("expected null, got value")
        return None
    else:
        if validate:
            data_type.validate(val)
        ret = val
    if alias_validators is not None and data_type in alias_validators:
        alias_validators[data_type](ret)
    return ret

    I can say it is now working every time without error.

     

    I'm sure you don't like the code being altered and I can totally understand that but if you think the code doesn't look like it will yeild any issues then I'm happy to do a pull request on github.

    Thanks! I'm glad to hear you got this working. I'll ask the team to take a look over to see if this is a change that should be added to the SDK.

Hi Greg,

 

What file is the version number in? i can't seem to find it.

 

the current code i'm using has evolved from the example you posted in another thread which was giving me the same error.

 

with open(localFile, 'rb') as f:

            CHUNK_SIZE = 4 * 1024 * 1024

            if fileSize <= CHUNK_SIZE:
                smallFileUpload(client, dpBG, localFile, destPath, overwrite, dispName, silent)

            else:

                upload_session_start_result = dbx.files_upload_session_start(f.read(CHUNK_SIZE))
                cursor = dropbox.files.UploadSessionCursor(session_id=upload_session_start_result.session_id,
                                                           offset=f.tell())
                commit = dropbox.files.CommitInfo(path=destPath)

                while f.tell() < fileSize:
                    if ((fileSize - f.tell()) <= CHUNK_SIZE):
                        dbx.files_upload_session_finish(f.read(CHUNK_SIZE), cursor, commit)
                    else:
                        dbx.files_upload_session_append_v2(f.read(CHUNK_SIZE), cursor)
                        cursor.offset = f.tell()
                if not silent:
                    if dpBG == "dpbg":
                        dpbg.update(100, "", "Upload Complete")
                        dpbg.close()
                    elif dpBG == "dp":
                        dp.update(100, "", "COMPLETE!")
                        dp.close()
                    else:
                        Notify(title=SubTitle, message="[COLORyellow]%s[/COLOR] Upload [COLORlimegreen]Complete[/COLOR]!" % (dispName), duration=4000, icon=ART_URL + 'ogdb.png')
                if xbmcaddon.Addon(thisAddonID).getSetting("backres_dbox_removelocal") == 'true':
                    try:
                        os.remove(localFile)
                    except:
                        pass

You can see the version by printing dropbox.__version__. The latest release is v8.2.0. If you're not already on that, please upgrade and try again.

 

If you are seeing this on the latest version, please share the whole stack trace. I can't seem to reproduce this issue with v8.2.0, and it's unclear in which line of your code this is occuring. Thanks in advance!

    Hi Greg,

     

    Thanks for getting back to me.

     

    I'm a tad confused. I get 0.0.0 when i print dropbox.__version__

      If it's printing 0.0.0, that should indicate that your copy was just pulled from master, as opposed to installed from a particular release.

      Do you know recall you got the SDK exactly? For example, if you cloned it, please pull the latest from master. Alternatively, please install the latest, e.g., using pip.

        Yes I had downloaded the master from github.

         

        I've now downloaded 8.2.0 but I'm getting the same error.

         

        Here is the stack trace.
