TypeError: 'NoneType' object is not iterable

Hi, getting the following error when I call nu.get_account_statements(). Has anyone seen this before? My unchanged daily script started erroring out yesterday. Maybe nubank's API has changed?

Traceback (most recent call last):
  File "/_/projects/numbers/finance.py", line 175, in <module>

This is a known issue, it seems that nubank is deprecating this endpoint in favor of the paginated one.

Can you try it and check if it works with you?

Opa, that was more work than I anticipated, since get_account_statements_paginated returns a different record structure 😀 . Below is a snippet to gather all records for past 4 weeks into account_rows (with similar structure as get_account_statements).

Thank you! I'll close this.

  DATE_ANCHOR = str(datetime.today() - timedelta(weeks=4)).split()[0]

  account_rows = []
  feed = nu.get_account_statements_paginated()
  account_rows += [e['node'] for e in feed['edges']]
  has_next_page = feed['pageInfo']['hasNextPage']
  while has_next_page:
    cursor = feed['edges'][-1]['cursor']
    feed = nu.get_account_feed_paginated(cursor)
    account_rows += [e['node'] for e in feed['edges']]
    has_next_page = feed['pageInfo']['hasNextPage']
    if account_rows[-1]['postDate'] < DATE_ANCHOR: break
