But now If i am using my credentials and my Model it is working fine.
But for others it showing error above pasted.

    Great question and one that can cause some challenges if the file/export is too big. I would recommend you get the chunk data first then use Python to iterate on each chunk. That should work. Here's a sample Python script to help you.


    import requests

    import base64

    import sys

    import json

    from getAuthentication import userBA

    from getGUIDs import wGuid, mGuid, fileID, fileName



    url = (f'https://api.anaplan.com/1/3/workspaces/{wGuid}/models/{mGuid}/' +

           f'files/{fileID}/chunks')



    getHeaders = {

        'Authorization': userBA

    }



    downloadHeaders = {

        'Authorization': userBA,

        'Accept': 'application/octet-stream'

    }



    getChunkData = requests.get(url,

                                headers=getHeaders)

    with open('downloadChunkData.json', 'wb') as f:

        f.write(getChunkData.text.encode('utf-8'))



    with open('downloadChunkData.json', 'r') as f:

        f2 = json.load(f)



    with open(f'{fileName}', 'wb') as f:

        for i in f2:

            chunkData = i

            chunkID = i['id']

            print(f'Getting chunk {chunkID}')

            getChunk = requests.get(url + f'/{chunkID}',

                                    headers=downloadHeaders)

            f.write(getChunk.content)

            print('Status code: ' + str(getChunk.status_code))

    Others export and mine has no difference in size, although they have small one.
    Json response is also ok but not including Key 'chunks' in others case
    Like this: 

     

    {'meta': {'paging': {'currentPageSize': 0, 'offset': 0, 'totalSize': 0}, 'schema': 'https://api.anaplan.com/2/0/models/1B10FCDB61144BDA8BE3E743448B49CF/
    objects/chunk'}, 'status': {'code': 200, 'message': 'Success'}}
