Platform: What platform / version?

Description:

Hey everyone,

I have an application that uses Redis in a production environment, but the service crashed during a call to the get_message method from PubSub with the following error (unfortunately I am not able to reproduce the error after several attempts):

  File "/usr/local/lib/python3.10/dist-packages/redis/client.py", line 1056, in get_message
    return self.handle_message(response, ignore_subscribe_messages)
  File "/usr/local/lib/python3.10/dist-packages/redis/client.py", line 1098, in handle_message
    "data": response[2],
IndexError: string index out of range

Do you have any ideas on how this is possible?

Best regards,
Jorge
