Apache Nifi : ListSFTP Processor Failed to properly initialize Processor

[#1]

Hi, All!

I have a problem with NIFI ListSFTP processor. After started processor errored with

Failed to properly initialize Processor. If still scheduled to run, NiFi will attempt to initialize and run the Processor again after the 'Administrative Yield Duration' has elapsed. Failure is due to java.lang.IllegalArgumentException: A HostProvider may not be empty!: java.lang.IllegalArgumentException: A HostProvider may not be empty!

ListSFTP processor Version 1.12.0 and the Properties as follows:
