@danieltprice @bgrenon this is a user facing error message. Do you think the period should be substituted for a colon or something else? Lower case starts to sentences are annoying to me 😄.

Unless this is going against a wider convention, period is ok. But then the next sentence also needs to be fixed with a starting Cap and period.
