問題文
A flow uses the File connector's Read operation to load an invoice file. The next component must log the name of the file that was read. Where does that name come from?
選択肢
- From the payload, because Read returns an object that holds the content and the name.
- From a variable that the connector creates automatically using the configuration name as a prefix, so that several Read operations in the same flow do not overwrite each other's metadata as the event moves forward.
- From the connector configuration, which records the last file it touched.
- From the attributes of the message, which the File connector fills with metadata about the file such as its name, its path and its size.
