I have a Mule flow that reads files through a generic inbound endpoint from an ftp server, makes some modification on the data, and writes files through a generic outbound endpoint to an sftp server. Yesterday it processed 60 files. On 57 there were no errors, but on three the following traces appeared. Any suggestions are welcome.
Error writing data over SFTP service, error was: Failed to open local file
4: Failed to open local file
