Connection aborted.', RemoteDisconnected('Remote end closed connection without response')

[SaadEddineSaad97]

How can we help?

Hello All,
using the python onesignal SDK , and while sending push notifications to our application users, sometimes we receive Connection aborted.', RemoteDisconnected('Remote end closed connection without response') .

api_response = OneSignalClient._api_instance.create_notification(notification)

when checked the documentation i found that when calling create notification we may face 429 too many requests ( it may be the reason) .

I tried to reproduce it but i didnt arrived to do .

Any idea ?

We are using onesignal-python-api==2.0.2

Hey there, sorry this issue's gone stale. Upon testing I wasn't able to reproduce this problem myself, as it could be the case that you hit a rate limit. This would depend largely on how you are creating notifications -- I would need to see a more detailed example to be able to say.

I'm going to close this issue for now but if you have further questions, please feel free to comment back or open a new issue with more detailed instructions on how to reproduce this issue.

Thanks.
