Hi Harikanth, would you be able to take a look at the PR?

Hi, Sorry for the late reply. Actually I was using the Polaris in wrong way. I was calling the "Start-Polaris -Port 8080" at the end of the script. And when I run it 2nd time it use to throw that error. This was the script I am using "PolarisGet3-v1.ps1" Add-Type -AssemblyName System.Web New-PolarisGetRoute -Path "/getdata" -Scriptblock { $response.SetContentType('text/html') #$html = . "C:\Users\harikant\Documents\ProjectFMC\Content.ps1" $Html = . "C:\Users\harikant\Documents\ProjectFMC\mainTest.ps1" #$Html = . "C:\Users\harikant\Documents\ProjectFMC\mainTest-v2.ps1" $Response.Send($Html) } New-PolarisPostRoute -Path "/home" -Scriptblock { $Response.SetContentType('application/json') $Body = [System.Web.HttpUtility]::UrlDecode($Request.BodyString) $Data = @{} $Body.split('&') | Where-Object{ $part = $_.split('=') $Data.add($part[0], $part[1]) } $Response.Send(($Data | ConvertTo-Json)) } #Start-Polaris -Port 8080 I have one question. If I make some changes to mainText.ps1 script and run PolarisGet3-v1.ps1 do I need to this clear the route using this command "Remove-PolarisRoute" and run PolarisGet3-v1.ps1? Regards, Harikanth

If you want to try the code in PR #200 it should let you call Start-Polaris multiple times without any negative effects.

To answer your question though you can either use Remove-PolarisRoute -Path '/home' -Method POST and then re-add the route with New-PolarisPostRoute -Path '/home' -ScriptBlock ... or you can add the -Force parameter to New-PolarisPostRoute to tell it to overwrite an existing route.

@Tiberriver256 Thanks so much for your answers.
It is working as expected now. This question can be closed.

I used the code from PR #200 but had to remove $Hostname from
$this.InitListener($Port, $Https, $Auth, $Hostname) (line 267 and 276) in order to make it work
