Setting a Variable Through API

I’m trying to set an array variable’s value through a POST to the /api/v1/variable and having minimal luck. Every time I do it the value gets reset to System.Collections.ArrayList and the type gets reset to String.

I’ve also noticed that the GET method requires you to run it through a PowerShell CLI XML converter (i.e. ConvertFrom-PSFClixml).

Can the variable endpoint be updated to be more REST API-like?

# Example of retrieving an array value
$previousParams = @{
    Uri = 'https://localhost/api/v1/variable/teams'
    Headers = $adminHeaders
}
$teams = Invoke-RestMethod @previousParams | Select-Object -ExpandProperty value | ConvertFrom-PSFClixml

# How I would expect to have to interact with this (no ConvertFrom-PSFClixml)
$previousParams = @{
    Uri = 'https://localhost/api/v1/variable/teams'
    Headers = $adminHeaders
}
$teams = Invoke-RestMethod @previousParams | Select-Object -ExpandProperty value

# example of TRYING to update, but unable to do so successfully - 
# the string value matches the retrieved value when the set through the UI

$resetParams = @{
    Uri = 'https://localhost/api/v1/variable'
    Method = 'PUT'
    Body = @{
        name = 'Teams'
        value = ([Object[]]@('a', 'b', 'c') | ConvertTo-PSFClixml -NoCompression)
        type = 'Object[]'
    } | ConvertTo-Json
    ContentType = 'application/json'
    Headers = $adminHeaders
            }
Invoke-RestMethod @resetParams

# How I would expect to interact with this

$resetParams = @{
    Uri = 'https://localhost/api/v1/variable/teams'
    Method = 'PUT'
    Body = @{
        value = @('a', 'b', 'c')
    }
    Headers = $adminHeaders
}
Invoke-RestMethod @resetParams
