Error Exporting MailBox with New-MailboxExportRequest from CSV

Hi everyone.

I have an error with New-MailboxExportRequest command  trying to export  some mailbox reading from csv file.

Its the script:

        

[cmdletbinding()]
Param()

Add-PSSnapin Microsoft.Exchange.Management.PowerShell.Snapin
. 'C:\Program Files\Microsoft\Exchange Server\V15\bin\RemoteExchange.ps1'
Connect-ExchangeServer -Auto

$csvfolder = "$home\desktop"
$csvName = 'Libro1.csv'
$csvdata = Import-Csv $(Join-Path $csvfolder $csvName) -Encoding UTF8
$date = ((Get-Date).AddMonths(-3)).ToShortDateString()


if ($csvdata) {
$tot = $csvdata.Count
$actual = 0
    foreach($record in $csvdata){
        $sede = $record.Sede
        $fileP = "\\172.22.3.23\C$\testbackup\"+$sede+".pst"

        $actual++
        $perc = $actual * 100 / $tot
        Write-Progress -Activity 'Generating Export Requests' -Status "Generando exportación de $($record.Cuenta)
            ($actual of $Tot)" -Percentcomplete $perc

        New-MailboxExportRequest -Mailbox $record -ContentFilter "Received -lt '$date'" -FilePath  $fileP
    }
}

It says the following:

Cannot process argument transformation on parameter 'Mailbox'. Cannot convert value "@{Cuenta=comunicaciones.fmm; Sede=Sede23}" to 
type "Microsoft.Exchange.Configuration.Tasks.MailboxOrMailUserIdParameter". Error: "Cannot convert hashtable to an object of the 
following type: Microsoft.Exchange.Configuration.Tasks.MailboxOrMailUserIdParameter. Hashtable-to-Object conversion is not supported 
in restricted language mode or a Data section."

    + PSComputerName        : prubmmcdpexc01.testbmm.com

Please, help me.
