Thank you for additional comment.
But when i call with scroll_id="" i caught error message "Validation error (Integer size parameter greater than 1 should be provided when working with scroll)" .
so I tried to call with scroll_id=1 however i still got same error.

if it is correct way to increment page, i will use this way like example in the following https://github.com/allegroai/clearml/blob/master/examples/services/cleanup/cleanup_service.py

I'm not sure what's wrong, but you should simply use the session's send_request() method to send this request, don't use requests.post yourself

StraightParrot3 how exactly did you call it?

Thanks.

I changed my code using session.send_request() not using requests.post() .
session = clearml.backend_api.Session() payload = { 'only_fields' : ["id", "name", "project", "completed", "user"], 'page' : 0, 'page_size' : 5, 'scroll_id' : 1, 'order_by' : [ 'completed' ] } response = session.send_request("tasks", "get_all", json=payload) response.json()but still I got same error.

and I also tried APIClient
from clearml.backend_api.session.client import APIClient client = APIClient() tasks = client.tasks.get_all(page=0,page_size=10) tasksit gives following response and it works.

when i call with scroll_id, and then the error occurred with unsupported arguments scroll_id.

Hi StraightParrot3 , page increment is indeed correct in this case.
To use scroll_id, you will need to start the call by specifying scroll_id="", size=<some int>

Hi StraightParrot3 , page_size is indeed limited to 500 from my understanding. You need to scroll through the tasks. The first tasks.get_all response will return scroll_id , you need to use this scroll_id in your following call. Every call afterwards will return a different scroll_id which you will always need to use in your next call to continue scrolling through the tasks. Makes sense?

Thank you for your reply.
I tried following code. however i couldn't find scroll_id in the response.
` session = clearml.backend_api.Session()
url = r"{}/{}".format(session.get_api_server_host(), "tasks.get_all")
payload = { 'only_fields' : ["id", "name", "project", "completed", "user"],
'page' : 0,
'page_size' : 10,
'order_by' : [ 'completed' ]
}
response = requests.post(url, data=json.dumps(payload), auth=(session.access_key, session.secret_key))
response.json()

'trx': '9ab21d7d66f84da6bdb8aa37141fe83b',
'endpoint': {'name': 'tasks.get_all',

'name': 'hyper-parameters example',
'project': '57f9a10d127f44ffa192cb36cd6de8fe',
'user': 'allegroai'}]}}

10 results `

I requested to get 5 results at once and repeat it with page incremented,
payload = { 'only_fields' : ["id", "name", "project", "completed", "user"], 'page' : 0, 'page_size' : 5, 'order_by' : [ 'completed' ] }
payload = { 'only_fields' : ["id", "name", "project", "completed", "user"], 'page' : 1, 'page_size' : 5, 'order_by' : [ 'completed' ] }
I could get same 10 results.
how can i get scroll_id ?
Is page increment way in above correct way?
