Bad Request - SessionError: No sessions

[Gabriell Henrique]

Sometimes some instances start to return this error:

{
"status": 400,
"error": "Bad Request",
"message": [
"SessionError: No sessions"
]
}

And I am forced to restart the api. Is there any way to definitively resolve this?

I started to recieve Bad Request.

400 - "{\"status\":400,\"error\":\"Bad Request\",\"message\":[\"The \\\"f6a22162-263b-45d1-99e3-84876afc6103\\\" instance does not exist or is not connected\"]}"

in production, but locally works

Hey guys, the only solution I found was to start the API with a cron that restarts it every 6 hours, if it gives this error, it will "correct itself" when restarted. Unfortunately it's not the best way, but it's a solution.

pm2 start 'yarn start' --name WhatsAppAPI --cron-restart="0 */6 * * *"
