rest-api/data/send - возвращает 500 "Internal Server Error"

[Gennadiy Ostanin]

При попытке отправить data/send приходит 500 ошибка, причем работает через раз. Иногда нормально отправляется и приходит статус 200, а иногда приходит 500
data = {
"nodeId": "",
"sessionId": session_id,
"operationId": "",
"payload": {"type": type, "value": data}
}
res = requests.post(settings.WCS_HOST + "rest-api/data/send", data=json.dumps(data), headers={"Content-Type": "application/json"})

Причем при повторной отправки тогоже самого data, на n-ый раз приходит 200 и всё отправляется.

В чем может быть причина, что 500 приходит через раз?

Добрый день.

Это означает, что клиент с таким sessionId не подключен. Возможно, у клиента проблемы с каналом, и он успевает отключиться к тому моменту, как ему будет отправлено сообщение. Для того, чтобы проверить, что клиент подключен, используйте REST API запрос /connection/find с поиском по sessionId, например

POST /rest-api/connection/find HTTP/1.1
Host: localhost:8081
Content-Type: application/json
 
{
    "sessionId":"/192.168.1.102:39564/192.168.1.101:8443"
}
