Invoke-SwisVerb : Verb Orion.AlertSuppression.SuppressAlerts cannot unpackage parameter 0 of type System.String

Try sending the $entityUris by itself and not wrapping it as an array so:

.... SuppressAlerts $entityUris

Hi,

It doesn't seem to matter how I pass the parameter, the following all fail:

Invoke-SwisVerb $swis Orion.AlertSuppression SuppressAlerts "swis://myserver.mydomain/Orion/Orion.Nodes/NodeID=29"
Invoke-SwisVerb $swis Orion.AlertSuppression SuppressAlerts $entityUris
Invoke-SwisVerb $swis Orion.AlertSuppression SuppressAlerts @($entityUris)
Invoke-SwisVerb $swis Orion.AlertSuppression SuppressAlerts (@($entityUris))

Ahh I should have caught that. The verb needs 3 paramaters in the array.

1) entity uri

2) start time Utc

3) end time Utc or $null .. not providing this param may be the same as providing $null with the end result of an indefinite mute

So this should work:

$now = (Get-Date)::UtcNow

$2hoursFromNow = $now.AddHours(2)

.... SuppressAlerts @($entityUris, $now, $2hoursFromNow)

Hi,

Thanks for looking into this, but I am still getting the same error. See logs:

This is an example that I used just yesterday, and it works on Platform version 2022.3.

$NodesToMute = Get-SwisData -SwisConnection $SwisConnection -Query "SELECT Caption, Uri FROM Orion.Nodes WHERE IPAddress LIKE '10.149.%.%'"

# We are in the central time zone, right now, so those are reflected in the hand-typed entries below
$suppressFrom  = Get-Date "2022-09-17 01:00 AM" # 11 PM, Friday - Los Angeles Time
$suppressUntil = Get-Date "2022-09-18 04:00 PM" # 5 PM, Sunday  - Los Angeles Time
# Flip them to UTC
$suppressFrom = $suppressFrom.ToUniversalTime()
$suppressUntil = $suppressUntil.ToUniversalTime()

Invoke-SwisVerb -SwisConnection $SwisConnection -EntityName 'Orion.AlertSuppression' -Verb 'SuppressAlerts' -Arguments $NodesToMute.Uri , $suppressFrom, $suppressUntil

Hi - do you have any more ideas on this? 

What does your powershell code look like (start to finish) now, could you provide it? This works for me without issue...

Hi, 

I am going to wait until we update our Platform/SDK Versions, and then test this again. Thanks for your help.

My tests have been running on SwisPowerShell version 3.1.0.343.

Thanks, I think our Platform/SDK version is pretty outdated - so I'm not sure if Suppressing/Muting alerts is supported in this build. For now I can unmanage a node fine. Once we have updated I will test again and report back. 

Please also provide what version of the SolarWinds Platform you are connecting to.  

It's available at the bottom of any page after login.

Hey, yes this is pretty outdated as well -  2020.2.6.

Pretty sure that should still work, but maybe you'll just need to update the SwisPowerShell module.
