server.tasks.get() call does not properly handle interval of 24 for daily refresh tasks in Tableau Cloud #1354

Closed Maitredata closed 6 months ago

Maitredata commented 9 months ago

Describe the bug Basically, if we set up a daily refresh on Tableau Cloud, the Tableau Server Client receives an hourly interval of 24. We can see the value returned in Postman. However, according to the code (link below) the VALID_INTERVALS set does not contain 24 as a valid value.

Source: https://github.com/tableau/server-client-python/blob/master/tableauserverclient/models/interval_item.py#139 Line 139: # VALID_INTERVALS = {0.25, 0.5, 1, 2, 4, 6, 8, 12}

This results in a stack when a task has a daily recurrence, rather than a more frequent hourly

Versions

To Reproduce

  1. Log into your Tableau Cloud site
  2. Set up an extract refresh task on a Daily interval. Settings used from the configration are Repeats: Daily, Every: Day At: ANY, Days ANY
  3. Run script below (see sample code) to pull a server.tasks.get(), stack will occur.
  4. (Optional) check the equivelant call on Postman or another API, using the {{server}}/api/3.17/sites/{{site luid}}/tasks/extractRefreshes call and you'll see the expected value is 24, but the stack indicates the value is not part of the valid intervals set.

Results

Code run:

import tableauserverclient as TSC

siteID = ""
tokenName = ""
tokenSecret = ""

tableau_auth = TSC.PersonalAccessTokenAuth(tokenName, tokenSecret, siteID)
server = TSC.Server('', use_server_version=True)

with server.auth.sign_in(tableau_auth):
    tasksResponse = server.tasks.get()
    print(tasksResponse)

Here's the stack received:
