Method PUT IN Powershell, Issue: 400 Malformed Error Converting,

When running the script in Powershell, the Invoke-RestMethod PUT command outputs

> Invoke-RestMethod : 400 MalformedCONTENTThe data request is malformed. Required content is missing or empty.Could not acquire data. 

 + Invoke-RestMethod -Method PUT -Uri http://##.##.###.#:8022/reader/bl ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo          : InvalidOperation: (System.Net.HttpWebRequest:HttpWebRequest) [Invoke-RestMethod], WebException
+ FullyQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeRestMethodCommand

Changed the parameter (as told by user below) to: 

$headers3 = @{
Host          = "##.##.###.#"
Authorization = "Basic Jlytuwhazkfnrfhdskldmxzaaldkjgpoiudtr"
Accept        = "application/json"
}   

$body = @{
       'payload' = @{
             'sensorId'   = "ee:16:as:ea:de:963"
             'blinkCount' = 5
             'blinkOn'    = 500
             'blinkOff'   = 500
             'countPause' = 2
             'timeout'    = 5000
                    }    
}

$jso = $body | ConvertTo-Json
Invoke-RestMethod -Method PUT -Uri http://##.##.###.#:8022/reader/blink-led -Headers $headers3 -Body $jso

I have changed the $body parameter multiple times and still couldn't get the output in Powerhsell. The parameters works since I have tested the parameter on Rest Client, RESTer.

You're mixing PowerShell and JSON notation in your $body definition.

Change this:

$body = @{
    sourceName = "Anything here";
    sourceId = "Anything here ";
    sourceIP = "##.##.##.###";
    sourcePort = ####;
    datetime = "###############";
    payload = {
        monitors = [
            "REST response time",
            "Authentication failures"
        ]
    }
}

into either this:

$body = @{
    'sourceName' = 'Anything here'
    'sourceId'   = 'Anything here '
    'sourceIP'   = '##.##.##.###'
    'sourcePort' = ####
    'datetime'   = '###############'
    'payload'    = @{
        'monitors' = 'REST response time',
                     'Authentication failures'
    }
}

or this:

$body = @'
{
    "sourceName": "Anything here",
    "sourceId": "Anything here ",
    "sourceIP": "##.##.##.###",
    "sourcePort": ####,
    "datetime": "###############",
    "payload": {
        "monitors": [
            "REST response time",
            "Authentication failures"
        ]
    }
}
'@
