56: Annotated text missing

The left curly bracket { is used together with the right curly bracket } for annotating content with a hint. The text to be annotated is expected to be found immediately before the left curly bracket. However, there is either whitespace or no text at all before your left curly bracket.

Solution

Make sure the left curly bracket is placed directly after the content which is to be annotated, without whitespace in between. If you did not mean to annotate content but want to use curly brackets literally, you can prepend backslashes: \{ and \}

If you meant to create a multiple-choice option – these are made with curly brackets at the start of a line – make sure that the whole block starts either with text without block markup or with curly brackets for the first option already. Make sure that further curly brackets that mark further options are always located at the start of a line.
