19: Content missing in target

You set or referenced a target with the characters # or ^. Targets are required to contain textual, numeric or non-ASCII content, which your target does not. Aneamal marks such as ~ and punctuation marks like ? do not count as content in this context.

Solution

Set a target that contains an emoji, letters or digits for example: #kangaroo. If you did not mean to use a target, but want to use the # or ^ characters literally, you can prepend a backslash: \# \^
