I am trying to extract data from SAP using OData and python. I am trying to extract only 200 000 data using requests.

The code:

# Data Chunk Settings
 dataChunkSize = 50000  # Number of records per request
 num_iter = 4  
 output_folder = "<folder_name>"


 url = "{0}:{1}/sap/opu/odata/sap/{2}/{3}?$format=json".\
       format(sapHostName,sapPort,odpServiceName,odpEntitySetName)

 s = time.perf_counter()
 try:
   num_iter = num_iter
   for i in range(1,dataChunkSize*num_iter,dataChunkSize):
     if i == 1:
       url_i = url + "&$top={0}".format(dataChunkSize) + "&$skip=0"
       print(url_i)
       data = requests.get(url = url_i,sapUser=sapUser,sapPassword=sapPassword)
       if data.status_code == 200:
         data_f = json.loads(data.text)#["d"]["results"])#.decode('utf-8').replace("'",'"')
           with (os.path.join(output_folder,'file_1st.json'),'w') as j:
             json.dump(data_f,j,ensure_ascii=False, indent=4)
     else:
       url_i = url + "&$top={0}".format(i+dataChunkSize-1) + "&$skip={0}".format(i)
       print(url_i)
         data = requests.get(url = url_i,sapUser=sapUser,sapPassword=sapPassword)
         if data.status_code == 200:
           data_f = json.loads(data.text)#["d"]["results"].decode('utf-8').replace("'",'"')
           with (os.path.join(output_folder,'file_{0}.json'.format(i)),'w') as j:
             json.dump(data_f,j,ensure_ascii=False, indent=4)
 except Exception as e:
   print(str(e))
 elapsed = time.perf_counter() - s
 print(f"Execution time: {elapsed:0.2f} seconds.")

When I run the above code, I get the below error:

'tuple' object does not support the context manager protocol

Not sure why I am getting this. What am I missing? Is the error related to json.loads() part?
