Re-run SQL on error - sql

Question

I am building a PowerShell script to clean up the hundreds of batch file executions and scheduled tasks that I have running on my machine.
One of the processes that I am cleaning up is a connection to a remote SQL server that downloads .csv files onto a network location.
It works over and over again and then I receive the following message
Exception calling "Fill" with "1" argument(s): "ExecuteReader: CommandText
property has not been initialized"
At L:\Operations Database\BatchScriptExecutions\PS\Scripts\0000 - 0100\ControlsBrokerRec.ps1:2426 char:1
+ $SqlAdapter.Fill($DataSet);
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [], MethodInvocationException
+ FullyQualifiedErrorId : InvalidOperationException
I am wondering what I can do to re-run the process if this error occurs? Is there a way in PowerShell to loop on error?
The code that is running is multiple iterations of the following:
## - Runs Script from Set Location
$SqlCmd = New-Object System.Data.SqlClient.SqlCommand;
$SqlCmd.CommandTimeout=$timeout;
$SqlCMD.CommandText = $CL3CASHPOSITIONSSCRIPTWINS;
$SqlCmd.Connection = $SqlConnection;
## - Extract Data and build sql data object
$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter;
$SqlAdapter.SelectCommand = $SqlCmd;
$DataSet = New-Object System.Data.DataSet;
$SqlAdapter.Fill($DataSet);
$DataSetTable = $DataSet.Tables["Table"];
## - Check for Null Return of Data into table
if ($DataSet.Tables["Table"]) {
$isnotnull
$DataSet.Tables["Table"] | Export-Csv $CL3CASHPOSITIONSEXPORTWINS -NoTypeInformation
echo "Cash Wins"
} else {
echo "NULL NULL NULL"
}
The issue happens so sporadically that I am unsure how I can test solutions for this. I am assuming that there should be some kind of catch statement within the code, but I'm at a loss.
