since the latest update my pieced together script that i put to gether using other peoples scripts has stopped working.  i have tried and tried to figure out what is wrong and also tried switching to v1 api but no luck,  below is a sanitized copy of my script and was really really hoping someone could help.  it changes the wifi password on a scheduled basis for guest wifi.   any help is very much appreciated.   param([string]$site="",[string]$ssid="",[string]$action="")   [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.SecurityProtocolType]::Tls12 -bor [System.Net.SecurityProtocolType]::Tls11                # change path below for password file name     $chgpw = get-content "C:\Users\removedusernameforsecurity\Desktop\update meraki wifi passwords\password.txt"                   function updateWiFiPSK ([string]$s_id, [string]$w_id, [string]$chgpw) { [Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12   # PSK = New password $data = @{ "psk" = $chgpw }   #Convert data to Json format $jbody = ConvertTo-Json -InputObject $data   #Combine base URL and ssid $request_uri = $base_uri + $networks_uri + $s_id + "/ssids/" + $w_id   $r = Invoke-WebRequest $request_uri -Method:Put -Headers $header_org -Body $jbody   return $r }   function Get-SiteID     {     #get site id     $request_uri = $base_uri + $networks_uri     $r = Invoke-WebRequest $request_uri -Method:Get -Headers $header_org       $json = $r | ConvertFrom-Json     for($i=0;$i -lt $json.count;$i++)         {         if ($site -eq $json[$i].name)             {                        $s_id = $json[$i].id             }         }       return $s_id     }   function Get-WiFiSSID ([string]$s_id)     {     #get wifi network ID from site requested     if ($s_id -ne "")         {         $request_uri = $base_uri + $networks_uri + $s_id + "/ssids/"         $r = Invoke-WebRequest $request_uri -Method:Get -Headers @{"X-Cisco-Meraki-API-Key"="removedkeyforsecuritytopostonline"} -ContentType "application/json"           $z = $r | ConvertFrom-Json           for($i=0;$i -lt $z.count;$i++)             {                        If ($z[$i].name -eq $ssid)                 {                                 write-output $z[$i].psk > c:\trash.txt                 $w_id = $z[$i].number                 }             }         }       return $w_id     }       # setup some global static stuff $base_uri = "https://editedforseurity.meraki.com/api/v0/organizations/ideditedforecurity/" ##    E.G.   n34.meraki.com/api/v0/organizations/<OrgID>/ $networks_uri = "networks/" #Meraki API KEY $api_key = "keyeditedforsecurity" $header_org = @{"X-Cisco-Meraki-API-KEY" = $api_key;"Content-Type" = 'application/json'}   $s_id = "" $w_id = "" $mode = ""   If ($site -eq "" -or $ssid -eq "")     {     Write-Host "MerakiPSKTool - (c) 2019"     Write-Host ""     Write-Host "Site/SSID parameter is missing"     Write-Host "Usage: MerakiPSKTool.ps1 -site <sitename> -ssid <ssidName> -action [Change | Display]"     Write-Host ""          exit     }    # if action not passed or is blank, set default mode to Display if ($action -eq "")     {     $action = "Display"     }   switch ($action)     {     {@("Display", "display") -contains $_ }         {             "Displaying Wifi details"             $mode = "display"         }          {@("Change", "change") -contains $_ }         {                          $mode = "change"         }       default { "MerakiPSKTool.ps1" }     }     # get ID of the site passed in params (set a default value if no site passed) $s_id = Get-SiteID   If ($s_id -ne "")     {     # get id of Wifi network that password is to be changed for     $w_id = Get-WifiSSID($s_id)       #Write-Host "Site ID      : " $s_id " | Wifi #: " $w_id     }    if ($mode -eq "change")     {          $result = updateWiFiPSK $s_id $w_id $chgpw                       }     else         {         Write-Host "Password change failed for " + $ssid + " at " + $site         }     ...
