Fixes bug #4445

[nicoddemus]

Hi @viveksoundrapandi,

First of all thanks a lot for taking the time to contributing to the project, the team definitely appreciates it! 😁

Unfortunately this is not the correct approach; not your fault at all, unfortunately the thread in #4445 was left hanging and it was not clear to those involved how to proceed.

I just included an explanation in #4445 (comment), hopefully that makes it clear what the issue is about.

I'm closing this now because unfortunately I think this needs to be restarted from scratch, but please don't let this discourage you from trying again, either on this issue or another one from our issue tracker. 👍

Thanks for the details @nicoddemus .
