Question

У меня запущено приложение, которое получает данные с устройств IoT, у меня начались проблемы, когда мой бункер Orleans полностью зависает, и он запускается снова только после того, как я вхожу в командную строку. Когда я нажимаю кнопку ввода, это обычно приводит к некоторым ошибкам DynamodB (я использую DynamoDB для постоянного хранения). Я получаю несколько ошибок при записи, чтении и проверке сбойных исключений, таких как:

Amazon.DynamoDBv2.Model.ConditionalCheckFailedException: условный запрос не выполнен ---> Amazon.Runtime.Internal.HttpErrorResponseException: удаленный сервер возвратил ошибку: (400) неверный запрос.

System.Net.WebException: удаленный сервер возвратил ошибку: (400) неверный запрос.

Существуют ли какие-либо известные ошибки в DynamoDB или я могу еще попросту решить эту проблему, чтобы получить больше информации?

Myrtue · Answer 1 · 01 мая 2019

Я не нашел ничего более конкретного в ошибках динамодаба, но, похоже, это вызвано зависанием бункера.

Видимо, командная строка зависания бункера была из-за режима быстрого редактирования: https://serverfault.com/questions/314194/why-does-windows-command-prompt-stalls-until-a-key-is-pressed-when-executing-lon

Отключение режима быстрого редактирования, похоже, решило мои проблемы.
