Import ssaw (error)

I use Python 3.11.4 and installed ssaw already but when I imported it I got the error below. Does anyone facts this problem and how to resolve it?

ok, whats the url you are using? check if that url exists and if its the same as your survesolution web access

Thank you for reply.
I use the folowing Python Script to download the data from our server.
import time
import ssaw
from ssaw import ExportApi
from ssaw import export
from ssaw import QuestionnairesApi
from ssaw.models import ExportJob

def main():
clientA = ssaw.Client(“MyOwn server:9700/”, “AppUser”, “Password”, “Workspace1”)
for q in ssaw.QuestionnairesApi(clientA).get_list():

   args = {
       "questionnaire_identity": str(,
      "export_type": "Stata",
      #  "export_type": "Tabular",
       "interview_status": "All"}

   response = ExportApi(clientA).get(**args)
   if not response:
       # there is no ready export, start a new job
       job = ExportJob(**args)
       job = ExportApi(clientA).start(job)
       # check status every 1 second until the status is not 'Completed'
       job = ExportApi(clientA).get_info(job.job_id)
       while job.export_status != "Completed":
        job = ExportApi(clientA).get_info(job.job_id)

       # the job was completed, try to download if file was created
       if job.has_export_file:
           response = ExportApi(clientA).get(**args)

if name == “main”:

have you checked that the hostname and port are correct? like check it in a web browser and copy the same one,

Since the specific error code 500 was mentioned, it tells me that this was the actual response. You are expected to have a different error code (perhaps 404) if the query was sent to just some incorrect address or port number.

The server’s log should contain the information on the specifics of the error.


@sandeepbhujbal have you checked if there’s really data to export? on stackoverflow just read that “graphql sends the HTTP error 500 whenever detects there is no data returned.” so, maybe check that the specific data you are trying to export exists on ssolution (try a web via ux export)

Dear team.
Is this a server version problem?
We use the server version 21.01.5 (build 30686).
