Thanks!

I had trouble transferring large stacks due to the api request being cut off (and thus being invalid json). A quick hack to fix this:

def get_response(url):
    response = requests.get(
            url,
            auth=authFrom,
            headers=headers, stream=True, timeout=30)

    response_content = []

    for chunk in response.iter_content(101024):
        if len(chunk)>10000000:
            response_content.append(chunk)
            response.close()
            break
        else:
            response_content.append(chunk)
            break
    return json.loads(response_content[0])


def getStacks(boardId):
    return get_response(f'{urlFrom}/index.php/apps/deck/api/v1.0/boards/{boardId}/stacks')

Hey there!
Awesome Script! Thank you so much for your work! Unfortunately I ran into an error:

File "/usr/lib/python3/dist-packages/requests/models.py", line 943, in raise_for_status
    raise HTTPError(http_error_msg, response=self)
requests.exceptions.HTTPError: 403 Client Error: Forbidden for url: https://mydomain.tld/index.php/apps/deck/api/v1.0/boards
User@server:~/import/nextcloud-deck-export-import$

Thank you in advance!

I use a cloudflare tunnel for this domain… Could that be the problem? Is there a way to enter the ipaddr without a certificate?
