  • Hi Andrew, The comment can be placed in the original question by using "Edit". Could you also expand on the issue you are having? Describe in the edit what you are attempting to do and any error messages you receive. – Matt Jun 09 '22 at 04:01

  • You should print the actual error message, not a static text "Connection Failed Via Connection String.", i.e. `console.log(err.errmsg)` or `console.log(err.message)` – Wernfried Domscheit Jun 09 '22 at 08:44
