Unterminated string starting at

Im getting a strange error. Im currently using seedcross and get this error with your API. Im unsure of why.

here is the traceback.

Traceback (most recent call last):
  File "/usr/local/lib/python3.8/site-packages/qbittorrentapi/decorators.py", line 161, in wrapper
    result = response.json()

    obj, end = self.scan_once(s, idx)
json.decoder.JSONDecodeError: Unterminated string starting at: line 1 column 239700 (char 239699)

During handling of the above exception, another exception occurred:

qbittorrentapi.exceptions.APIError: Exception during response parsing. Error: JSONDecodeError('Unterminated string starting at: line 1 column 239700 (char 239699)')

Any idea what the cause could be?

so i had that script running for over 24 hours and have not seen the issue once.

I also have not replicated the issue with seedcross. I have a feeling that the issue is that when i first run seedcross it overloads the qbittorrent instances as so many new torrents are being added and being rechecked and thats the cause of the Unterminated string since the qbit is so overloaded.

i think its best to close this for now and Ill reopen if i can re-produce.

BTW thanks for the prompt responses and the excellent help.

hmm…interesting. That suggests the problem is likely intermittent…and as such makes it much harder to track down. Additionally, the dictionary for each torrent that is returned from client.torrents_info() do not contain much dynamic content other than changing statistics; so, that does make me wonder if special characters could really be the root cause given I wouldn’t expect them to be appearing and disappearing in this payload…

Nonetheless, another option is just to run client.torrents_info() in an infinite loop:

from time import sleep
import logging
import qbittorrentapi

logging.basicConfig(level=logging.DEBUG, format='[%(asctime)s] {%(name)s:%(lineno)d} %(levelname)s - %(message)s')
client = qbittorrentapi.Client(host='localhost:8080', username='admin', password='adminadmin', VERBOSE_RESPONSE_LOGGING=True)
LOOP_INTERVAL = 3  # seconds

while True:
    for idx in range(len(client.sync.maindata()['torrents'])):
        print(client.torrents_info(limit=1, offset=idx))
    sleep(LOOP_INTERVAL)

You can change LOOP_INTERVAL to have it run as often as you like. And the loops will break out as soon as there’s a problem; so, no need to watch it. The exception will be the last thing printed once one occurs.
