Returning data calling function from invoke-command with parameters - function

Question

Apologize for the length..
Trying to modify a script that currently uses robocopy to report a folder path's size, child folder count, and size. This script currently takes about 24 hrs to run as it goes one by one to each folder. I'm trying to implement invoke-command to set-up jobs so that it will run at least 10 instances of robocopy in the hopes if drastically reducing run time.
I've tried multiple variances given multiple resources to set parameters, call a function and get the results back with no success.
with current code (below) getting error;
Invoke-Command : Parameter set cannot be resolved using the specified named parameters.
ERROR: + Invoke-Command -ScriptBlock { param ($item,$Filter,$params) $ ...

When all said and done I have a collection of $Report to show folder name, count of files, count of folders, size in bytes, and comments tho show any errors to Excel
$Report | Sort-Object {[long]$_.Size} -descending | Select 'Folder Name', Files, Folders, Size, Comment | Export-Csv -Path $ReportPath\$(Get-Date -uformat "%Y_%m_%d")-FileSizes.csv -Encoding ascii -NoTypeInformation
