A couple of things that you need to do here, that Workspace needs to be made Public as part of the whole challenge so you might as well change that now via the Workspace Overview > Settings.
Once you have done that, you can share the full URL of the Workspace so that people can see exactly what you have in place.
The challenges require you to perform tasks within the Collection, if you’re having issues that’s what you need to share and not the static request with the validation checks in it.
Those don’t change so that’s not much use when sharing that you have a problem.
Show full images of the things that you have changed/added and not images of the test failures from the submit requests, as they don’t mean anything in isolation.
