SyntaxWarning: invalid escape sequence '\s'

[simone80an]

I have latest Rundeck OSS 5.8.0 running in a Windows Server 2019 VM, Python version installed 3.13.1 and latest py-winrm-plugin v.2.1.3.

When i execute a Powershell script i made i get SyntaxWarning: invalid escape sequence '\s' in the output.

The script:

if (Get-Service -Name "@option.servizio@") {
$arrService = Get-Service -Name "@option.servizio@"
Restart-Service -Name "@option.servizio@"
write-host 'Restarting service @option.servizio@'

Start-Sleep -seconds 10

$arrService.Refresh()

if ($arrService.Status -eq 'Running')
{
    Write-Host '@option.servizio@ is now running'
} else {
    Write-Host '@option.servizio@ is stopped, notifying...'
    exit 1
}

} else {
    Write-Host "@option.servizio@ service doesn't exists."
}

the option servizio has the following list of allowed values: NETA Schedulatore Amministratore Service,NETABollengWrapperService,Neta Etl Service,NETA Reports Service,NETA OutputFile Service

The output:

C:\rundeck\libext\cache\py-winrm-plugin-2.1.3\common.py:35: SyntaxWarning: invalid escape sequence '\s'
regexpMultipleAbsolutePath = re.compile(''[a-zA-Z]:\\.\s[a-zA-Z]:\\.') #at least two absolute paths
C:\rundeck\libext\cache\py-winrm-plugin-2.1.3\common.py:39: SyntaxWarning: invalid escape sequence '\s'
regexpPathAndOption = re.compile(''[a-zA-Z]:\\.\s/.+')
C:\rundeck\libext\cache\py-winrm-plugin-2.1.3\common.py:43: SyntaxWarning: invalid escape sequence '\s'
regexpPathAndOptionUnix = re.compile(''[a-zA-Z]:\\.\s-.+')
C:\rundeck\libext\cache\py-winrm-plugin-2.1.3\common.py:47: SyntaxWarning: invalid escape sequence '\s'
regexPathRequireQuotes = re.compile(''[a-zA-Z]:\\.*\s')
Riavvio servizio NETABollengWrapperService
NETABollengWrapperService è ora in esecuzione

However the job complete OK and the script does what i expect.
