Loop through SQL files in powershell - sql-server

Question

I am trying to loop through each sql file in a folder and run the script on a database. This is what i currently have.
#Provide SQLServerName
$SQLServer ="xxx\xxx"
#Provide Database Name
$DatabaseName ="xxx"
#Database User
$User ="xx"
#Database Password
$Password ="xxx"
#Scripts Folder Path
$FolderPath ="\\xxxs\xxx\xxx\xxx\"
#Loop through the .sql files and run them
foreach ($filename in get-childitem -path $FolderPath -filter "*.sql")
{
invoke-sqlcmd –ServerInstance $SQLServer -Database $DatabaseName -Username $User -Password $Password -InputFile $filename.fullname
#Print file name which is executed
$filename
}
When this runs i get the following error
At C:\Agent\_work\8\s\Deploy\dbRun.ps1:15 char:21
+ invoke-sqlcmd â?"ServerInstance $SQLServer -Database $DatabaseName
-Username ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~~~
The string is missing the terminator: ".
At C:\Agent\_work\8\s\Deploy\dbRun.ps1:14 char:1
+ {
+ ~
Missing closing '}' in statement block.
+ CategoryInfo : ParserError: (:) [], ParseException
+ FullyQualifiedErrorId : TerminatorExpectedAtEndOfString
I cannot figure out what I'm missing causing this error. I see the close }
