Coldfusion Secure FTP there is an error in the file if the file does not exist?

Question

I am trying to use the secure FTP function ColdFusion. I run the error using a function fileExistsonly when using a secure connection. Instead of returning "no" when the file that was transferred does not exist, instead the errors say:

"An error occurred during the sFTP existsFile operation.

The system cannot find the path {file name} "

A regular FTP file works fine (the same code as below, but with a different connection).

If the file exists, then there is no problem, and the file will be deleted and written.

I feel that this is a mistake, but I confirm that I am not doing something wrong or that something is missing.

<cfftp action="open"
    connection="ftp_connection"
    server="#this.server#"
    port="#this.port#"
    username="#this.username#"
    password="#this.password#"
    fingerprint="#this.fingerprint#"
    secure="yes"
    />

<cfftp action="existsFile"
    connection="ftp_connection"
    remotefile="#arguments.remote_name#"
    directory="/"
    />

  <cftry>
    <cfif cfftp.returnValue EQ "Yes" or cfftp.returnValue EQ "true">
      <cfftp action="remove" 
        connection="ftp_connection"
        item="#arguments.remote_name#"
        />
    </cfif>

    <cfftp action="putFile"
      connection="ftp_connection"
      passive="true"
      localfile="#ExpandPath('/vctemp/#arguments.local_name#')#"
      remotefile="#arguments.remote_name#"
      />
