Error with PowerShell and XML settings file for WinSCP Protocol setting

2019-02-22 16:38

Hi everyone
I get this error:

The value supplied is not valid, or the property is read-only. Change the value, and then try again.

If I hard code the value it works fine. I've checked the value is being pulled from the xml file by doing a write-output and it's fine. The other values work fine, it's just the Protocol. I've tried all four combinations of "" around the value. Any ideas? Huge thanks. Adam

# Setup session options
$sessionOptions = New-Object WinSCP.SessionOptions -Property @{
    #Protocol = "[WinSCP.Protocol]::Ftp"
    Protocol = $configfile.settings.FTPServerSettings.protocol
    HostName = $configfile.settings.FTPServerSettings.hostname
    PortNumber = $configfile.settings.FTPServerSettings.portnumber
    UserName = $configfile.settings.FTPServerSettings.username
    Password = $configfile.settings.FTPServerSettings.password
}
 
$session = New-Object WinSCP.Session

settings.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!-- setting file for use with WinSCP -->
<settings>
   <FileSettings>
      <LogFile>E:\WinSCP\Bentley</LogFile>
   </FileSettings>
   <FTPServerSettings>
      <protocol>[WinSCP.Protocol]::ftp</protocol>
      <hostname>ftp.blahblah.co.uk</hostname>
      <portnumber>21</portnumber>
      <username>blahblahblah</username>
      <password>blah</password>
      <ftpsecure></ftpsecure>
      <tlshostcertificatefingerprint></tlshostcertificatefingerprint>
   </FTPServerSettings>
<!--   <FileDownload>

PowerShell won't convert string "[WinSCP.Protocol]::ftp" to enumeration value [WinSCP.Protocol]::Ftp. But it will convert simple "ftp".

But now I have the same problem with the TlsHostCertificateFingerprint, this time even when I hardcode the string PowerShell rejects it with the same error message:

Error: The value supplied is not valid, or the property is read-only. Change the value, and then try again.

Any help very gratefully received
Adam

All fixed now. I was using TlsHostCertificateFingerprint instead of SshHostKeyFingerprint in the session options.
All fixed – Thanks for reading.
