VB.NET MySql Store Procedure

It is my first time having to call a mysql store procedure from vb.net. I am trying to use the below code but it keeps saying

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'SP_Validate_user' at line 1

What am i doing wrong? The store procedure does not show any problems. It commited successful

Imports MySql.Data
Imports MySql.Data.MySqlClient
 
    Public Shared Function validate_user_credentials(ByVal username As String, ByVal password As String) As Boolean
        Dim myConnection As New MySqlConnection
        myConnection = New MySqlConnection(myConnectionString)
        Dim myCommand As New MySqlCommand("SP_Validate_user")
        myCommand.Connection = myConnection
        myConnection.Open()
 
        myCommand.Parameters.AddWithValue("Username", username)
        myCommand.Parameters.AddWithValue("UPassword", password)
 
        Dim sqlReader As MySql.Data.MySqlClient.MySqlDataReader = myCommand.ExecuteReader
        While sqlReader.Read()
            MsgBox(sqlReader(0))
            MsgBox(sqlReader(1))
        End While
        myCommand.Connection.Close()
 
        sqlReader = Nothing
    End Function
