Do not tell lies. You are not giving the exact code nor the exact error. You have "sanitised" both to the point that they do not provide the information we require to provide informed help that directly addresses the problem you are having. There are a multitude of possible mistakes that could result in the type of error you describe. While we can, and do, guess which mistakes are most likely, we can't give a definitive answer if you give us inaccurate fuzzy information.

Do you want help? If so, give us good information!
