Calling SQL Server stored procedure from powershell - sql-server

Question

I'm trying to call a SQL Server stored procedure from PowerShell but I always get errors on parameters.
Stored procedure has 8 parameters, all with default values
#simchain nvarchar
#idSimulation int
#idCompany varchar
#modelName nvarchar
#simDate datetime
#mySim int
#statusFloor int
#statusCap int
From Management Studio I can call this procedure even without any parameter, so just executing EXEC [dbo].[E_simulations] works.
From PowerShell I create a connection and a command but I always get an error on missing parameters, for example
Procedure or function 'E_simulations' expects parameter '#simchain', which was not supplied.
Here is my test code (just to test proper execution)
$SqlConnection = New-Object System.Data.SqlClient.SqlConnection;
$SqlConnection.ConnectionString = $ConnectionString;
$SqlCommand = $SqlConnection.CreateCommand();
$SqlCommand.CommandText = "EXEC [dbo].[E_simulations]";
$SqlConnection.Open();
$returnedValue = $SqlCommand.ExecuteNonQuery();
Am I missing something?

I have made quick test. I hope this will help
Made test proc:
CREATE PROC doTest (
#param1 INT = 1,
#param2 VARCHAR(10) = 'xxx'
)
AS
BEGIN
PRINT 'THIS ONE'
SELECT 1 As Data
END
Find PowerShell code, which executes proc:
$SqlConnection = New-Object System.Data.SqlClient.SqlConnection
$SqlConnection.ConnectionString = "Server=localhost;Database=ForTests;Integrated Security=True"
$SqlCmd = New-Object System.Data.SqlClient.SqlCommand
$SqlCmd.CommandText = "doTest"
$SqlCmd.Connection = $SqlConnection
$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter
$SqlAdapter.SelectCommand = $SqlCmd
$DataSet = New-Object System.Data.DataSet
$SqlAdapter.Fill($DataSet)
$SqlConnection.Close()
$DataSet.Tables[0]
Execute result gave this
Data
