Azure Data Factory Pipeline для копирования нескольких таблиц завершается ошибкой

Question

Мой первый пост, заранее извините, если я делаю что-то не так

Я следовал инструкциям, приведенным ниже в документе Microsoft, и создал фабрику данных для копирования данных нескольких таблиц из On-Prem база данных в Azure база данных.

здесь

конвейер завершается с ошибкой:
